I'm really liking this idea for Camp Rockaway, a sort of camp/beach club for the subway-riding beach set of New York.
"Camp Rockaway means you don't have to end your day at the beach with a hot subway ride home. Unwind in a hammock. Send a postcard or browse the visitor's guide to see what else Rockaway has to offer."
I'm in if there are fruity rum drinks.
