Nantucket Island - 30 miles out to sea.  Best time to come is in June or September.  Take the long ferry ride to the island.  When you arrive you feel as if you are in paradise.  It's the best place to be.  Plenty of sunrays, breezes, morning fog,  dark-blue waters, flowers everywhere, cobble-stoned streets, history and the best food anywhere.  I suggest staying at the White Elephant, Harbor House, Nantucket Landfall, Wauwinet, Century House, Corner House.  Ride your bike everywhere.  The nightlife is amazing. These are fun activities that you can remember forever. You will never regret it.
