Has anyone here been to an adult tennis camp? Do you think it was worth it for your game? I'm sure they're worth it from a vacation point of view, but in a few days, were you able to take your game up a notch? I like the idea of a camp, where a pro might get to see you for an extended period of time... trying to get some real opinions though. Oh, and what level are you and where did you go? Thanks.
