Can recommend two places on St. Thomas...
1. Marriot Frenchman's Reef -- pretty high-end, but you get what you pay for. (15+ minutes to Charlotte Amalie Ferry Terminal)
2. Best Western Emerald Bay -- walking distance from the St Thomas airport (or a *very* short cab ride). Not as nice as the Marriott, but a fantastic beach with great snorkeling. A little funky, but still decent. Not inexpensive, but cheaper than Frenchman's Reef. (10 minutes to Charlotte Amalie Ferry Terminal).

I stayed at both earlier this summer before and after a charter out of BVI. The Mooring's Mariner Inn looks like nothing special -- no beach, a mediocre pool and waaaay overpriced restaurant.
