Thursday - Look around Chatham, boat trip to Monomoy Island
Friday - Passenger ferry from Harwich to Nantucket - Island tour - back evening
Sunday - Plimoth Plantation
Monday - Marthas Vineyard from Hyannis and island tour
Tuesday - Drive back to Boston - should we visit anywhere en route as we had the car in when we get to Boston.
Sorry such a long post and thanks in advance for help,
