We'll be in Orleans...
I have a feeling I will not be swimming in the ocean, anytime soon
Orleans is great; off main street (route 6a) is a little shop my buddy owns called Cape Eclectic, just neat little things by local artists and some antiques, I can get you the address if you like that stuff. Also look up the Hot Chocolate Sparrow for some nice treats.
Follow the tide charts and hit the beaches early when the sandbars are out, plus if you don't get to the beach before 8 you won't be parking anywhere near the water.
