Will be in Cape Cod for the first time over Labor Day weekend and would love some recommendations of things to do, places to see, places to eat. We'll be staying in West Yarmouth, which looks like a good central location. We'll have a car, so can get to places easily. Would love to go to Martha's Vineyards for a day, but otherwise don't know what else to do. Please recommend nice places to explore as well as good places to eat (preferably no tourist traps). Thank you!
