Winnetu Oceanside Resort shared by @cntraveler says: ""This classic Martha’s Vineyard resort boasts a great location on Edgartown’s South Beach, plus a teen adventure program that includes activities like kayaking, bridge jumping, mountain biking, and a ropes course. While the kids are off getting their adrenaline fix, the adults can lounge at the beach and grab lunch poolside before regrouping at the resort’s Cape Pogue cottage."" on Postcard
