For a surprise my wife and son booked us 2 nights at the Race point light house in provincetown on cape cod. It was awesome. A private non profit has restored the light keepers house and turned in in to a sort of bed & breakfast inn. Its situated out in the dunes at the very tip of cape cod.
You need to make reservations way in advance visit their website at http://www.racepointlighthouse.net and check it out you can sit on the porch and stare at the ocean or walk on the beach and thru the dunes
You can also go up inside the light house and read about its history
