It’s the better choice for families who want resort programming and entertainment on site.
When The Island Inn on Martha’s Vineyard wins: choose The Island Inn if you want to stay on Martha’s Vineyard near Oak Bluffs, prefer a smaller property with cottage-, condo- and studio-style rooms, and plan to spend more time exploring island beaches, trails, and town life rather than using big resort amenities.
