The Renaissance on St. Thomas is not bad, but it's a little far away from everything and I got a little tired walking up the hill to the room.
Morningstar and Frenchman's Reef are in the same location. Both are right on the beach, but Morningstar is literally 30 feet from the water. Both are very nice, but I would try to get an upgraded view at Frenchman's if you end up there.
Highly recommend Craig & Sally's and Hotel 1829 restaurants. Daytrips to St. John or British VI's are great.
The Cancun and Aruba Marriott's are also very nice and a new JW Marriott Cancun opens shortly and has some cheap rates. I haven't stayed at any of the others.
