Really curious as to what you find as I am hoping to move to St. John's in about 4 years. Have a fun trip!

I went scuba diving in St. John this past summer and we loved the dive company we used, Cruz Bay Watersports. www.divestjohn.com/ I would highly recommend them. They only took certified scuba divers on the trip. The dive master was really great and pointed out a lot of things I would not have noticed. I went with my brother and his family who had just been certified and the dive master made sure my 12 year old niece was doing great and having a good time. We used one of the other dive companies on St. John for a kayak trip and it was disasterous. We ran into someone on our dive boat that had friends that went with the other dive company, and they had disasterous experience as well. Sorry, I did not dive out of St. Thomas so I can't recommend anyone there. If you're not sure where you are staying yet, I recommend the Concordia Eco-Tents for a low cost beautiful place to stay. There are pictures of them in my profile.
