Assuming you are looking for places to stay, as opposed to tech stops, I have had great experiences on Long Island, at Cape Santa Maria. You fly into Stella Maris (MYLS), and they will pick you up. It is a beautiful little resort, nothing fancy, just beautiful beach, nice bungalows, good food, great fishing and snorkeling.
I want to go back!
I always tried to bring enough fuel into MYLS to return to Florida, and then bought a bit as a courtesy from the FBO there, because sometimes the fuel barge didn't show up or whatever, and I didn't want to be stranded there.
I'm hoping to go back in a year or two. It's a long haul from the west coast, but my son lives in the northeast, so not so bad for him, and we are not quite as locked into school schedules as we once were.
