My husband and I and another couple (early 30's) will be visiting Nantucket in mid October, the weekend after Columbus Day. We have never been to Nantucket before. How many nights would you suggest staying? We are looking to do some activities, shopping, eat, drink and relax. We have 4 nights to be on vacation, and were considering spending 3 nights on Nantucket and then going somewhere else within an hour or so drive of the Cape Cod area for our 4th night? Any suggestions as to whether we should just stay on Nantucket for the 4th night or if not, where we should go for our final night? Looking for quaint, pretty small towns with nice restaurants, antiques, and great views. Thanks!
