From shingled, mansard-roofed inns to gingerbread-laden Victorian mansions, Martha's Vineyard accommodations reflect the island's past. Choose a location to fit your mood: Edgartown for a dignified historic ambience, Oak Bluffs for lively nightlife, or up-island to commune with nature. Many hotels are open only in-season, from April or May through October. High season is June-August; if you plan to visit during that time, make reservations well in advance, especially for weekends.
