Just got back from a short trip to St. Thomas. Took a day trip to the north side of the island and checked out Coral World. Pretty interesting. They have an 80,000 gal tank and even better, an undersea observatory. Felt like snorkeling but without getting wet. Worth the $15 (w/ $3 coupon) and you can hang out at the nearby Coki beach for the rest of the afternoon.
Worth checking out if you're in the Virgin Islands.
