The Westin St. John Resort & Villas Rating: 3.5 Pearls
The Westin St. John is the best kid-friendly resort in the U.S. Virgin Islands. Children receive personalized amenities like coloring books or bath toys and are treated to complimentary beverages at mealtimes. The supervised kids' club ($60 per day) -- for ages three to 12 (it's four-and-up at other hotels) -- offers daily activities like sandcastle contests, movies, and swimming. And teen-interests aren't neglected: They can keep busy at the 1,200-square-foot Westin Teen Center or with activities like parasailing, kayaking, tennis, and salsa lessons.
Caneel Bay Resort Rating: 4.5 Pearls
Caneel Bay lacks an elaborate pool or even TVs in the rooms, but it has one of the best, and rarest, of kid-friendly amenities in the Virgin Islands: free supervised activities. Kids three to 12 can spend the day participating in arts and crafts, treasure hunts, and nature walks through the activity center, Turtle Town. Plus its location -- in the midst of the Virgin Islands National Park -- offers ample hiking and outdoors activities.
Sugar Bay Resort and Spa Rating: 3.5 Pearls
A cool grotto-style pool, fun water activities like bumper boats, and the "Kids Klub's" scavenger hunts, snorkeling, and iguana feeding ($95 per day) make the Wyndham Sugar Bay the best family resort on St. Thomas, especially since families can easily fit into the large standard rooms (available with two double beds or free rollaways).
