They enjoyed dressing up in fireman gear, playing with water, doing crafts, playing in the pretend food area, building with blocks, making bubbles, and playing outside. This place has a lot to do and we wished we could have stayed longer. Only part that is annoying is the stroller rule. If your child CAN walk, you can't take your stroller in. Weird rule for a place that caters to kids, including younger ones in that in between stage. Even cmy 4 year old gets tired more than average. And sure, my youngest can technically walk but he can't last the whole time walking. Anyway, we had fun but I felt like I couldn't fully relax.

We did the full cup package so it wasn't cheap... so just know you're paying for the experience, not the ingredients as one other post calls out. :-) We had 19 kids and Kevin who was running the show did did a great job of wrangling that pack of crazies. We brought food and the parents kinda got kicked out of the main area which was great. We hung out in the mall and got to have some adult time (but were still close enough if the kids needed something).

They created a custom outdoor play experience at the park for the kids to explore, play, and stay engaged during the party. It was such a unique and fun addition to the celebration, and so many parents asked for their information afterward. Highly recommend Otto Family Club for birthdays, family events, and anyone looking to create a fun and memorable experience for kids!

What a fun place! Otto Family Club is a lovely addition to Sunnyvale. I took my 2yo to a class and…read moreI was thoroughly impressed. The teachers meticulously plan out the sessions and they post the themes well in advance on Instagram. There are structured activities but also other toys for free play if your kiddo isn't feeling it that day. The best part is that you don't have to clean up afterward!! The location is on the second floor of the building. There's some parking right in front, but also plenty of street parking. There's only downfall is that they currently don't have classes on the weekends for working parents, but I hear some will be offered soon!

My son has been coming to the 6-9 class for the past few months, and I honestly can't say enough…read moregood things about our experience. The owners are wonderful people with strong values, and you can tell they genuinely care about every kid who walks through their doors. It's not just about learning ninja skills. They intentionally invest in the kids' character too. At the end of each class they do a short character lesson on things like humility, obedience, and other life lessons. As a parent, I really appreciate that they're helping build both confidence and character. Within just a couple of weeks, I noticed a huge difference in my son. He used to be nervous about things like the monkey bars, and now he's climbing, hanging, and excited to try new obstacles. It's been really fun to watch that confidence carry over into everyday life outside of class. My daughter also did a trial of the Sidekicks class for 2-3 year olds, and she absolutely loved it. It was the perfect mix of movement, exploration, and play for her age. Both of my kids have tried gymnastics, and while they enjoyed it, this has been a completely different experience. The classes change every week, so they're never doing the exact same thing twice. The obstacle layouts are always different, which keeps the kids engaged and excited to come back. Between the monkey bars, running walls, balance obstacles, rope swings, and everything in between, there's always a new challenge. Another thing I really like is that the kids are evaluated on their skills and can continue progressing through different levels. It gives them something to work toward while still making it all about having fun. Last thing, they have huge windows for the parents viewing area and they have a play section for the siblings. Our 3 year old daughter has fun with magnifies and blocks while her older brother is in class. If you're looking for an activity that builds confidence, challenges your kids, and keeps them moving, I'd absolutely recommend USA Ninja Challenge. We've loved being part of it.

They are patient, kind, encouraging to the kids, and very communicative for parents. Membership is monthly. You get 4 or 5 classes per month (1x/wk) with two make-ups per month if your child is ever absent. It comes out to ~$36.25/class per child - very reasonable for a solid hour of exercise and fun. The facility is spacious and clean with plenty of parking. Our children LOVE going to Ninja class every week. I can't recommend this place enough!

The kids absolutely loved the sensory tables -- it was one of the most popular stations all night. They were incredibly easy to work with, responsive, and reliable.

He invented different ways and stories to play these tables. These tables are very high-quality: clean, well-prepared, full of details, and mostly very fun. We have a sensory table at home, but the one here has much more details, like discovering all the snowflake treasures with Elsa. My son had so much fun with the tables. The booking process is also worry-free: just go meet and play and everything is already setup for you.

Happy Hollow is such a fun place for families with young kids! If you have little ones, this is a…read moregreat park to spend the day. There are so many rides designed just for younger children, and my son had a blast exploring everything. Our absolute favorite was the helicopter ride where you pedal to make your helicopter fly higher into the air. It was such a unique ride, and he couldn't stop talking about it! The outside play area was also much bigger than we expected and was adorable. It gave the kids plenty of space to climb, explore, and burn off energy. The petting zoo was another fun stop, and we loved the cute sand digging station next to the tortoise exhibit. While the animal exhibits aren't as large or extensive as some bigger zoos, the variety of rides and play areas more than makes up for it. Happy Hollow is really the perfect mix of a zoo and an amusement park for younger children. They also have a full café with plenty of options, including pizza, snacks, ice cream, and even healthier choices, so it's easy to spend the entire day without leaving the park. The only downside during our visit was that I wish more of the rides had been open. Even so, we had a wonderful time and are already planning another visit. Next time we'll arrive earlier so we can enjoy even more of what the park has to offer. Overall, it's a fantastic family destination, and we'll definitely be back!

Danny the Dragon and the rollercoaster ride were down for maintenance which sucked -- my oldest was most excited for these ones, we've never been before but in every video he's come across these are known as the "not to miss rides" He did however, enjoy/love all other rides which is the main reason for the 3 star review. Most animal enclosures/exhibits were covered. We saw no more than 10 animals here during our visit. My son was surprised this was called a "zoo" lol. It was super disappointing. The goat petting area was appreciated, it did keep my kids entertained for a bit. It was pretty busy for a Thursday but lines for the open rides moved quickly. The playground however, does get full quickly lol. It was a hit for my kids as well. Food: you're better off packing your own snack/lunch. It's self serve and quick which is appreciated but let's be honest, the quality was horrible. The cheeseburger was so hard to eat even my husband was disgusted. He had the grilled chicken sandwich and said it was "okay" My kids had macaroni and cheese, it was Kraft so couldn't mess up there lol. Pricing is also ridiculous but expected. We paid $60 for 2 burgers, 2 fries, 2 Mac and cheeses Overall, probably wouldn't return, it was an hour drive and just not worth it with all the closed down things, wish they mentioned this on the website -- only the rides are referenced

My kids came home and told me so much fun and kept talking about " green bean fly's recipes". It is 2 hours session and I was surprised how much they have learned. Neeba is very wonderful and patient with the kids. Also, the class is very well planned and organized. Each kid has their colorful little chef's outfit, chef's hat, note for recipes, and the kid's friendly cooking tools. The kids will learn how to take instruction, how to work together, and how to have fun and eat with their new friends. My kids already asked when they can join again. Thank you Neeba for hosting such a fun and educated workshop!

I saw they had open play this weekend, so we came with our toddlers and a few friends. It's a…read morepretty new indoor playground so everything appeared new and pretty clean. I was able to catch up with friends while the toddlers went wild. They especially loved the ball pit and the slide that goes right into it. There was a car repair station, a dress-up area, and a cow you could feed with a bottle. I have no idea how it worked, but the kids figured it out! They also had an automated zip line, obstacle courses for the kids to climb through, and a merry-go-round. The kids had a great time, and even after two hours of play, my son wanted to go back. The only downside is that weekend open play can be a little tricky. They announce availability on Tuesdays, and even then you're limited to whichever time slots are open. I'd definitely come back. Just remember to bring grip socks, or you can purchase a pair there.

We came here for a birthday party during a weekend afternoon. My son had a good time, but this…read moreplace isn't for everyone. In terms of the play area itself, it's awesome! The ball pit and slides are super nice and one of the best I've seen in an indoor playground around this area. The pit is spacious, pretty deep but not too deep, and the balls look clean and well-maintained (no broken/deflated balls). The pretend play area is really fun, too. I've never seen such a nice pretend makeup/vanity mirror. There were multiple mirrors, so less likely for kids to fight over, and cool pretend mascara / blush / eyeshadow / brushes. The cow milking station is the most unique, and I have to say it's kinda disturbing to me lol. But kids really loved milking the cow and feeding the baby cows the bottles. It is a little frustrating because the cows kept running out of "milk" periodically. The layout of the area is pretty nice when you're having a birthday party because you're not too far from the other parents so it's conducive to socializing instead of spending the whole time chasing after your kid. As for the negatives, and why I wouldn't recommend this place for every kid, I felt like there were too many rules. There were signs posted everywhere saying not to do stuff: don't take toys out of the pretend play area, don't take balls out of the ball pit, parents can't join the ball pit or jungle gym (unless your child is under 2), don't climb on this, etc etc.. I felt like the rules were way more stringent than other play areas. I understand that it keeps the play area neat / more fun for the kids if everything is in the right place, everyone is behaving etc, but this definitely wouldn't be a good place if your kid is neurodivergent or wild/noncompliant. As for the birthday party itself, attending as a guest it seemed a little messy because it was shared with multiple parties at once overlapping, and our food room was actually quite delayed because the party ahead of us was late and refused to get out in time. I've been to much more organized birthday venues.
