some arcade games are scams, the batting cages are horrible, the pitching machines only throw balls or really inside strikes, some of the balls aren't even hittable if you're a lefty. bathrooms are disgusting, mini golf is okay, dodgeball is short if youre in party and stuff, the pizza is above average I guess. the cherry Pepsi from the soda fountain tastes like it's watered down. only small or large sized drink. The credits you get for money to play games are overpriced. The batting machine balls are hard yellow balls that hurt a lot if you get hit by one, I got hit by one because it bounced off of my bat, onto the floor and into the side of my knee, now it's swollen and left a big mark. read more

The arcade is a decent size but MANY if not half of the games are out of order. The place looks pretty old and run down.

This place is great there are arcade games and the batting's cages are great people are saying false things about this place, and you can pay for 2 hours (or more or less) for throwing and practice catching or whatever you want, but people sign paper for the wait list and pls don't be one of those people that's just weird. But overall the place is great except for parents not caring about anyone but there kids going fist that's why I give 4/5 if it wasn't for the paper signing stuff it would be 5/6 read more

What is this place!? An arcade!? A sports center? I don't know. When you walk in you are greeted by a bunch of older arcade machines. Some were even covered with out-of-order signs. You are actually rewarded with real tickets, which was authentic though I haven't seen those in many years. The rewards themselves looked pretty bad and nothing a kid would really want. A rubber ball looked like one of the best prizes. They also have an indoor mini-golf black-light court and laser tag. I haven't seen either of these, though the laser tag was crowded and looked fun. I've here before for birthday parties, the reason I was here today, was that my buddy had a basketball game here. Their sports facility looked a bit outdated and small. A basketball court made up of plastic tiles that may be regulation size on a good day. The hoops were located on the out of bounds line making it a safety concern. The scoreboard was tiny and the horn was way too loud. The spectators and players both had to sit on hard metal benches. Finally, they had one tiny overhead heater making the court area feel freezing. I didn't think I was coming to a hockey game. They have a bunch of automatic batting cages with different speeds that the ball can be pitched with. Overall, the place is okay and would be a good rainy day activity. read more

Grand Slam is an interesting hybrid. Part Dave & Busters with tons of arcade games that spit out tickets you can redeem for cheap crap from China. Part amusement pier with indoor black light mini golf and laser tag. Part bouncy place/sports court. Part indoor baseball batting cages. And, of course, place of many birthday party rooms. As the batting cages, which are very nicely done and well equipped, were packed, we headed over to the arcade area. I will say their machines were not as well maintained as others I've seen and often did not spit out tickets like they should, so it has a feel of a 'rip off'. BUT when you go to an attendant, they are more than happy to credit and were very generous in 'rounding up' the Young Un's ticket count thanks to some of these mishaps. Overall, it's a good spot for an off-weather day as there is a variety of things to do. You can walk to Friendly's which, while it doesn't share a parking lot, is directly adjacent, for food. Grand Slam has a 'snack bar' which serves food in the variety of hot dogs, pretzels, nachos and sodas. read more

Great place for kids to have fun with a variety of activities. Reasonable and truthfully adults can enjoy and play games as well. Joey and Chris helped us at the ticket booth and were very patient with our children! We will be back! read more

We just had our son's 13th birthday party here and it was a hit! Reasonable prices and EXCELLENT service from our party hostess, Erin. She was extremely attentive and helpful and kept our party moving with perfect flow. VERY pleased with everything and would definitely recommend Grand Slam for parties! On a slightly different note: I would like to address another reviewer here. The person that said they had great experiences with this business in the past but then had one bad experience so gave them a bad review. Why does everyone only choose to YELP when they have a BAD experience, but not with any of their good ones??? As a business owner myself, I can tell you that everyone is human and we all make mistakes. The correct way to handle things would be to go to the business owner and give them a chance to address your issue. Write a negative review if they are unwilling to try and resolve the issue for you. But for pete's sake, please write a GOOD review when you have a good experience! These reviews can really help or hurt a business and negative reviews can be very damaging to a family's livelihood so please THINK before you post! read more

I was there for a birthday party. The laser tag and ninja course were pretty good, but almost everything in the arcade was broken! Not counting the machines that already had "out of order" signs on them, I had problems with all of these: Deal or No Deal - There's a sign on the machine that says "$1.00 to play for 400 ticket jackpot or $2.00 to play for 800 ticket jackpot." Actually, $1 sets the jackpot at 200 and $2 sets the jackpot at 400 - half of what is advertised Sea Wolf - no tickets came out even when they were earned Big Haul - the game says 10 tickets for every coin in the truck bed, but it doesn't give you any.  One person opened up the machine and checked to make sure there were tickets.  I tried again, and still no tickets.  I talked to another person working there and she just said, "I don't know what to tell you." Big Bass Wheel - was giving no tickets.  I talked to someone working there, and she refilled the tickets, so I got mine, but I know several kids before me just lost their money without getting the tickets they earned. Gold Fishin' - you're supposed to get 12 ping pong balls to shoot, but the machine only had 11 in it.  So once it said "Balls Remaining: 1", you just have to wait until it times out. losing out on any points that 12th ball would have given you. Plush Bus (Claw machine)  I put in my money, moved the claw forward, moved the claw back, and pushed the button.  But the claw never lowered!  It just took my money and gave me no chance to try to get anything.  A little later they put an "out of order" sign on it. Air Hockey - the edges of the table are bent, so rather than the puck bouncing off the wall, it sometimes just gets stuck under the "lip" of the table and stops.  I guess it's still semi-playable, but really annoying. Ice Ball (Skee ball) - I had 3 tokens left, so I decided to try Ice Ball (2 tokens).  I put in 2 tokens and pushed start.  Nothing happened.  I put in my last token just in case one of the others didn't register, and pushed start.  Still nothing.  Money gone, no game - what an appropriate last game for the visit. Ticket Station/Eater - 3 of the 4 ticket counters had "out of order" signs on them.  I went to the only one that was working and put in 10 tickets.  It gave me credit for 7.  Then I put in 150 tickets, and it only counted 116 of them!  So it's short changing everybody's ticket count by ~25-30%!  I fed some more tickets into it (since there was no other option), and the machine broke!  I had to take my tickets to the redemption station and have them weigh them instead. I felt ripped off by the time I left, and it was too crowded to try to get an employee to fix most of the problems. This could be a really cool place if they put the necessarily time into fixing and maintaining their games. read more

Speaking about the batting cages only. I know this place is an "amusement park" and attracts a more family oriented crowd. Either way, the cages are in good condition and are rarely full. They are set up for slow, medium, and fast pitching (baseball and softball). Overall, a clean and cheap form of entertainment. read more

The Good: The batting cages were adequate for my teen daughter. Well that's about it, nothing else good to report here on my visit. The Bad: Well several of the video games had handwritten "out of order" signs. This is especially painful when you consider that there are not many options anyway. In addition, there is virtually nothing available for a 3-year old to play. Finally, at the end of it all there was no one to help at the counter to redeem for prizes...I had to ask someone at another counter. Overall this was a poor experience for me and my toddler. Next time I will stick with the place where kids can be kids. I rate this place a soft 2 stars only because of the batting cages and somewhat friendly staff. read more

I came here on a Wed afternoon to use the batting cages. They have 5-6 different cages. However it's indoors so you only see your ball go 50ft until it hits a black tarp. If your point is to see how far you can hit the ball then you're s.o.luck. read more

I can't speak high enough of this place! I took my son here to spend an afternoon away from his overbearing grandmother. I love her to death, but sometimes I wish she would find another PLACE TO LIVE. Anyways, he absolutely LOVED it! First we spend about an hour in the arcade playing the video games that gave out tickets that he later cashed in for prizes (Peanut M&M's and a whoppie cushun to be specific). He even got a Goetze for mommy :-P Next we played laser tag. Apparently Grand Slam just got a new laser tag system and arena this WEEK! What luck! The new system was great! It was very bright and colorful in the room and the laser guns talk to you during the game! I even could see my score on the screen. Maybe I should play against my mother sometime ;) ;) ;) Finally, we played a round of mini-golf. Their mini-golf course is indoor and black light. I've never seen that before! My son seemed like quite the pro though considering he had already played it with his friend Allen in Ocean City. If Allen wasn't such a terrible influence on him half the time, I "would" let him hang out with him more. My son only beat me by a few shots, so I had to treat him to a slice of pizza (which Grand Slam apparently makes right there in their building). It was no Papa John's, but a great slice nonetheless! All in all, I give Grand Slam a 5/5. The afternoon whizzed on by. Now back to the DAILY GRIND. See you again soon, Slammie Davis, Jr.! read more

The facility is filthy, bathrooms are so dirty I couldn't even use it. Their "nerf" war is awful, in a hot gym with no air. They build their walls from old plastic bins with holes. The Target is a red Solo cup. I pain 27 dollars a kid and was given 1 slice of Pizza. It was awful. I will never return. read more

First time at Grand Slam USA!! We went for Laser Tag and the staff was very helpful. I had called ahead to see what time the laser tag will be open to public (in between the b'day parties), they were right on time on their schedule and they managed to fit our group in. Will definitely go back!! read more

Was just here for a 6th birthday party. The activities they had planned for the kids were good. The facility itself was very dirty, the roof was leaking so most of the ninja warrior area was wet. The bathrooms were dirty, looked like they hadn't been cleaned in days. Half the aracade games were broken. I'm thankful I did not pay for this party, upset for the family that did. I hope they get a refund because the place was not worth the price they charge to have a party here. read more

I've always been a fan of Grand Slam and appreciate the support they've given to our Little League, however the private lesson service is seriously lacking in customer service. I signed my son up for 5 private lessons. After waiting for more than a week for an instructor to call, I had to wait another week to get scheduled. For the first lesson, the instructor was 20 minutes behind schedule, for the second lesson, he answered his phone in the middle of it. Last week, after waiting for a week for a call back, I had to drive round trip an hour to get my son there for a 5:30pm lesson only to find the instructor double booked. The manager apologized but the instructor didn;t have the courtesy to come out and apologize because he didn;t want to interrupt the student. I was given some batting tokens and told I would get a call to reschedule. It's been 5 days and no call. And the medium speed cage my son wanted to hit in that night was constantly jamming. I think the big problem is that Grand Slam uses a pencil and paper ledger to schedule the appointments and clearly some don;t get recorded. It might be time to use an inexpensive software application to ensure you don't waste hours of customer's time double booking. Very disappointed. read more

The worst with broken machines, more staff then customers and old fashioned oval floor fans to blow more hot air into the overheated place without ac. If you like the smell of must and mildew, this is the place. I had to walk out after a few minutes. read more

We just had my son's 7th birthday party here, and it was awesome. A few days before the party, they called us and went over everything. The day of the party, everything went smoothly. Our party guide, Chris, was really helpful. I had never been to this location, so this was a shot in the dark for me to plan my kids party here. We planned to do the ninja obstacle course and the nerf battles. Both were a hit. Surprisingly impressed, given the other poor reviews. read more

This place is terrible... went here with my daughter for the batting cages.. the employees were a bunch of kids standing around talking, not helping anyone.. cages were half out of order.. the other half are so inconsistent... no help from employees once again.. took other daughter into arcade.. total joke.. once again half (not even kidding) of the games were out of order. No employees walking around doing their job.. just a bunch of kids either on their phones or talking to each other.. beyond disappointed.... defiantly won't ever be coming here again. Don't waste your time or money.. they obviously don't try to fix things or care about the upkeep of the establishment. read more

Great place for families! We had a birthday party here a few months ago and it was fantastic. The staff was super helpful and everything went smoothly. Kids had a great time, and the price was very reasonable! read more
