This resort, set near one of the Vineyard’s best full-surf beaches, has more amenities than any other island resort—and prices to match. The rooms are all suites with one to four bedrooms. Winnetu is very much set up with families in mind. There is a children’s day program, a parent/toddler program, tennis club, heated swimming pools, a fitness facility, free fitness classes and yoga on the lawn, and, perhaps most important, shuttle transportation by land or water taxi to Edgartown’s Main Street. A nearby sister compound has home rentals and vacation condos.
