The staff had completely changed and it showed. The ONLY person that I would give more than 1 star to for customer service was Audrey...5 stars isn't enough. She was FANTASTIC! A GREAT dive master and a GREAT customer service representative of the company! She walked around on the boat before and after the dives and talked to everyone to get to know them and see how they were doing. Truly a model employee! That's where it ends. EVERYONE else was mediocre at best. No personality, no interaction with the divers, no customer service skills. Sam was no help in the dive shop, the captains were just there for the paycheck...it was a complete turnaround from the staff that was there before. BY FAR, the WORST was May. She was the dive master on my third day of dives and was a complete and utter disappointment. She picked the WORST possible dive sites (NE side of St. Thomas across from Coral World at Thatch Cay), had ZERO personality or customer service skills, and was not ready to be leading divers. We spent the first ten minutes of the second dive swimming into a strong current and she had no clue. You could watch the rocks below and see that we weren't moving at all. She finally turned us around and we just flowed with it until the dive was over. No wildlife pointed out, no attempt at doing her job...it seemed like she was being burdened to have to take us out. Needless to say, I won't use RHDC again. If is wasn't for Audrey, I would give it 1 star. She was truly great at her job. The rest...not so much.

As a newly certified diver, this was my first ever open water ocean dive--I certified in a quarry…read moreand did one contained water "try scuba" dive in ocean before certification. This was a two tank dive near Buck Island off St. Thomas, one dive at Wye Reef and one dive at Cartanza Wreck which is actually three spots that are close together. Captain David took us out in the Tropic Diver II and Shelby was our dive master. The boat was clean, the equipment seemed well taken care of, and both Shelby and Captain David were extremely friendly and helpful. There was another dive master who had four non-certified divers on the other end of the boat. I had no interaction with them. This was an excursion booked through Carnival. This company goes by Underwater Adventure and Adventure Scuba and School. I mention this because the only way I found them to review since Carnival does not provide the name of the company was to do a search for the boat!!! There were four certified divers, an excellent number for a newly certified diver because both Shelby and my dive buddy took extra care to watch after me. During my two dives, I saw the nice reef, the wreck sites, a shark, an eel, a turtle, a lobster, several white sea urchins, one large black sea urchin, and lots of fish. Because it was my first dive I did not want to be distracted with a camera, therefore I'm not able to share what I saw. The attached photos came off the web. I highly recommend this company. I was nervous for my first dive but Shelby was reassuring and made sure I did everything safely. I can not say enough good about the experience!!!!

On this Holland America ship excursion, the diving was OK, but I was very surprised to see Aluminum…read more72cf scuba tanks being used instead of Aluminum 80cf tanks, which required adjusting my preset tank straps on my BCD. Although it was not a problem, I was just surprised to find these tanks on a Caribbean dive. In fact, this was the only dive operator I have used anywhere in the world that uses these tanks, but I doubt many of the divers had a clue at to what size tank they had. Although the air quantity was ultimately sufficient for the shallow, low dive time profiles (33.5 and 37 minute dives), I would have preferred to have Aluminum 80s, and longer dive times. In all fairness to the dive operator, this was a ship excursion with a lot of low experience divers on a very large dive boat, and they no doubt had a tight schedule to maintain. The crew did a nice job dealing with, and keeping safe, so many low experience divers. I would have rated this dive operator higher had they split the divers into compatible experienced divers to provide a better dive experience for everyone.

Fitting for fins and equipment takes a while. Good thing we arrived early (parking can be problematic) to get everything situated. The staff and crew of this shop are the most friendly and chill folks. Brett was awesome and chill with my teenage boys and eased and assured me they were in good hands. CDC also took underwater photos. We purchased the entire file of photos for $27. Worth it. Actually the shore dive and both dive was priceless and worth every penny. I would recommend Coki Dive Center for their dives in St Thomas.

They are competent, fun, and go to great lengths to make sure you're really comfortable with every aspect of diving. Even if you're kind of terrified by the idea of breathing underwater (what? It's scary!), you'll feel safe in their very capable hands. I went for PADI Open Water Diver certification with a group of 9 friends, all of whom had different levels of experience and comfort with diving. Arnaud, Tania, Shauna, and Carlito put us at ease right away with their easy-going yet professional attitude - all of us got plenty of personal attention, and they made sure we really learned and understood everything and didn't rush us through the exercises, even though we got a late start (our fault) on the first day. It's a lot of work over 3 pretty long days, but they kept it fun by joking around and telling us cool things about the island, and my husband (who had actually done open water certification before, but never mailed in his info to get the card) said they were much more thorough than the last outfit he did it with - important, when it comes to little things like being able to breathe! These guys, and particularly Tania, deserve some sort of medal for the way they handled me. I have tiny, crappy lungs and a healthy fear of the ocean, and after screwing up an exercise and gulping a bunch of water at 16' I declared myself DONE with scuba forever (even though Tania got a cleared regulator into my mouth so I could breathe almost instantly). When I didn't come back the next day, they pulled my husband aside and offered to work one-on-one with me to help me overcome my fear and get my SCUBA Diver Certification, which is kind of like Open Water Lite (you can dive up to 40 feet, with a guide). They could have easily just taken my money and walked, but they were genuinely invested in seeing me succeed. Tania worked one-on-one with me and was SO patient and kind: I had a freak-out almost as soon as I went under and she got me calmed down, had me practice surface skills, and then just swam around with me underwater and pointed out fish and turtles along the reef until I was comfortable enough to practice skills again. She has an incredibly nurturing, comforting vibe that comes across even underwater, and by the end of the day I was totally chilled out and excited about diving...a far cry from the hyperventilating mess who first entered the water! I honestly thought I would never dive again, but after working with Tania I actually ended up going back to finish up my Open Water Certification - with Isla Nena Scuba, of course!

They were able to answer all my random questions about the fishes we saw, as well as gave pointers on where to dive next. Arnaud has been diving for years and is more than willing to share what he knows to make the experience even more fulfilling. Equipment is top-notch, and he even provided snacks! If you are in Vieques and are in the mood for some diving, give Isla Nena Scuba a call and see if you can dive Arnaud's Reef (yes, named after the instructor himself!).

If you're looking for a nice relaxing day on a private island then this may be the trip for you!…read moreThis is a group tour that travels with more than just those you booked with. As long as 15 people are on the tour, they will take you to your Calebra. If less than 15 you stay local! There were well over 15 so we were able to tour Calebra. It was so beautiful! Once you get there, they pick you up on a ferry to take you to the boat . The boat travels for about an hour before getting to a private island and that is where you get the guided snorkeling or diving tour depending on what you selected! My friends and I did the snorkeling. As someone who can't swim (I know I know lol) I had a great time. The tour guides were very informative and helpful for all ages and swim levels. They do provide fruit, cold cut sandwiches and rum punch and when you stop . If you're looking for a "party" boat then this may not be for you. Don't expect lots of liquor and twerking etc it's a family type tour, Some of my friends were a bit disappointed by the price expecting that we'd stop somewhere that had a bar and restaurant but it was just a private island (we're in our high 20s low 30s). So idk I think it depends on your expectations but I was okay with everything and the service was great!

Never In my life did I think I would give a 1 Star but would not recommend this company. We…read morecontacted them weeks prior to our trip to inquire about getting scuba certified. We were told we had to first buy and complete the course work through PADI and from There they would do the water/ dive sessions and compete the certification. The shop also gets a kick back from Padi as work since it makes u select a dive shop where ur course work is sent to. Once we complete the course work, we each reached out to the dive shop about 2 - 1 1/2 weeks in advance to schedule the dates and times for the water sessions. We did not receive any type of response back from the shop. We attempted to message on whatsup as requested but still did not receive a confirmation or any type of communication. We called down to the shop, where we were told to just text them. We again tried to text the shop but did not receive any response. We flew to San Juan and arrived and immediately went to the shop, we were told to text them and they would get back to us.. we asked directly if they had availability and we were told they would check and get back to us via text.... A day goes by, we attempt to call and no response.. fully we get a text saying they are fully committed...... This was without doubt the worst type of un-reliable customer service and a refusal to communicate.. I would not trust this dive shop or operation. They should never have told us to use to do the course work with their shop and then refuse to complete our certification. Luckily Scuba Dogs next door came to our rescue when we told them about the horrible customer service we received. Just be aware this shop will not be reliable.
