I live on the island and as familiar as I am with it all, I would still enjoy a week stay at Tranquility. by far the prettiest part of the island. there are several boats going back and forth to town you can get on if you need to shop.
Sueno has a great restaurant for breakfast lunch and dinner and the Tackle box has a knockyoursocksoff cheese burger.
