Thanks, guys! We did spend a couple days in Newport once, and had a great time, but couldn't find much of a beach! Much more in the way of wharfs than beaches, at least in town. I thought it was very cool, but also insanely expensive. Maybe I need to check towns in RI outside of Newport, though. For the record, Mystic was one of my favorite destinations as a kid. Gotta wait until my kids are a little older, to take them back there, though.
I spent every summer of my childhood at the Jersey shore (LBI), and know it well. We still make a pilgramage to Ocean City for one or two nights each summer, to stay with family. Aside from the obvious problem of being a dry town, it's always a good time! Unfortunately, my wife is down on the Jersey shore, for some reason. She was too spoiled, as a kid. She does make one good point, though, in that Jersey has become very expensive for what you get. If I can go to Bermuda or Croatia for what it costs to rent a nicer place at the Jersey shore, I won't be visiting Jersey!
