I'm going to be staying in downtown Cancun for part of June. I would love to hit some tennis balls and maybe even play some racquetball. Anybody know of any public courts? Anybody interested in hitting some balls? I'm out of practice and out of shape, just wanting to get some exercise and have some good, clean fun. EDIT: I believe I'll be staying in the southwest part of town, off Calle Kabah, if that helps.
