I've been to cancun and alcupulco, and can say I don't really have the desire to go back. It was dirty, and everyone wanted a "tip". In line at McDonald's, manager walked out in the line and told us he'd move us up for a tip. Seriously, like it was a night club. A guy I know was pissing outside of a nightclub, and the cops took his shoes, watch, and $200. To each his own I guess, but those people are ruining a good thing, as tourism is easy business if you have warm weather, nice beaches, and a safe place.
