Highlight of our trip! - This was absolutely the highlight of the trip! Alex and Daron were so wonderful - funny and informative. They accommodated what we wanted to see and we got to see sea turtles, sting ray and tons of fish! Thank you for making this such a lovely trip - next time we will do the full day!

Do it!!!! - Don't pass up this experience. It is my family and I's first time to the island and this was our favorite splurge. No better way to see the islands in our opinion. Alex and Alex(aka Orlando) we spectacular in every aspect. I could go on and on, but I won't. If you are hesitating on booking, don't. You will not regret it!!!

First Private Boating Experience in St Thomas with Family - Captain Alex and First Mate Coleman were amazing!! Worked in getting pizza at the Pizza boat for us! Coleman shared so many fun and interesting facts about the islands. Our son does not swim well so we were challenged in this area but Alex and Coleman watched our son on the boat for a few minutes while Mom and Dad snorkeled for about 30 mins. Great experience and would do this again. This was a half day booking. We saw sea turtles, a sting ray and a sunken ship.

The adventure of a lifetime for the entire family! - This was the adventure of a lifetime for our family!! If you are looking for a family excursion for all ages this is the one. We are 5 kids (ages 6 to 11) and 5 adults...I'm the grandma...and we all had a blast! Captain Alex and Mr. Coleman treated us to some beautiful locations to snorkel. Each one had different things to see. Their knowledge of the area from the history of pirates to the homes of celebrities was enlightening and entertaining. Their concern for safety and eco-friendly environment made us all feel secure and cared for. I highly recommend the rum punch for those who like an adult beverage. The beers were cold and plentiful but the kids were delighted with cokes and water. We took the half day trip and brought snacks which helped the kids make it until lunch back on the cruise ship. We could have eaten at the restaurant at the dock but that would have conflicted with our pre-arranged transportation. Because our family didn't snorkel for very long, Captain Alex took us around several islands that allowed us to have a better understanding of the beauty of this location. We did get caught in a rain shower but he deftly navigated the boat to a more sunny area. The rain never damped our experience so if the forecast isn't good...don't worry! You'll be happy!! At the end of our week for spring break I asked each family member what they enjoyed the most from a day at Disney, the cruise ship and our excursions. This rated NUMBER ONE with EVERYONE! I totally agree!

Unforgettable Experience - We booked a private charter for my dads 60th and it was truly an unforgettable experience. Alex and Alicia went above and beyond to make sure we had the best time. They were incredibly knowledgeable on the best locations to see and snorkel at. They were also extremely attentive with making sure we always had what we needed - gear, drinks, snacks, anything! We’ll definitely be back.

Seas of the day charters - Basically, a very poor customer service experience. We hired a private charter boat for $2100 for 7 hours. Firstly didn’t have appropriate life jackets. Secondly every question asked was me with the rude answers. Didn’t customize any part of what we wanted to do. They were expecting us to stop for lunch and waste one hour of our time so they can have lunch. We even fed them some snack snacks that we had.. we were 25 minutes late so they got 25 minutes out from our time. It was a full day charter, 25 minutes more of their time would not have been a big deal , but they were hungry and they had to eat. Captain Maddie, and her colleague were rude, downright completely incompetent of hosting anybody. Not worth it, do not go with family and kids with them.

Terrible - Staff: The captain was very rude. Safety: did not have life vests for all. Told us only available upon request before the trip after leaving the port. Time: Ended the 7 hour trip in 6 and half hour Worst part was when a two year old cried the captain yelled at her and said “stop crying, we are not having that today”.
