Hiya everyone,=-)
Just wanted to support the previous posts for Blue Island Diver. The Marriott is an excellent hotel too (I had my honeymoon there).
Blue Island Diver will pick you up, just email Aitch and he'll sort if for you. This is a standard service.
It's a shame some belive St.T a 5-6 out of 10 for diving. I stuck with Blue Island Divers for their focus on their safe relaxed no time pressure approach to diving. Don't believe me, check out their GuestBook:

I love the reefs, but am a wreck enthusiast. I was attracted by their search and research approach to St. Thomas' diving. Blue Island Diver have found 11 wreck since starting their operation November 2000. I was impressed. My favourite wrecks were the WIT Shoal, WIT Service, and favourite reefs Sprat Point and the Fences (which has a cavern that brings you up inside the island) not for everyone but is easy to access at 20ft. I also liked that fact that they plan their further west dives around a slack tide window for max comfort and safety (unlike some other I could mention).
They have excellent dive sites pages. The sites marked with a star on their dive sites pages are the wrecks they have refound since 2000. For old geysers like myself, they also have Nitrox.

On accomodation they did have some dive-stay packages with hotels / guesthouses / condos / villas on their packages page (which I just noted has just been republished and updated with new options). The rates are cheaper than the accomodations normally published rates.
Hope you enjoy St. Thomas - i'll be back there.
Blow those bubbles,
