We are coming for two nights in the fall of 2017. We will have a half day when we arrive and a full day. We would like to take the ferry to Nantucket on the full day, and just have dinner/walk or drive around where we are staying. I looked at lodging in Nantucket and it was out of our price range. We found a nice place in Sandwich. Would it be practical to stay in Sandwich and drive to the ferry for our day in Nantucket? Also, is there a downtown area in Sandwich to walk and eat.?
