For many years we vacationed either on Cape Cod or Martha's Vineyard until one day our friends convinced us to take a day trip to Nantucket more than 20 years ago. After exploring the entire island on bicycle, Nantucket became a favorite place to spend summer vacations with our family. Unlike Martha's Vineyard, we were able to go to all the beaches and not worry about beach tags, parking, or going to a 'private' beach. All the beaches were spectacular and had plenty of room for our kids to play.
