No, no snakes. I didn't get sick yet, but my dad did. I went to the Gran Bahia Principe resort in Riviera Maya (I'm not sure if that's the town name or not though), and that's near Playa del Carmen, and a 2 hour car ride from the Cancun airport. Rick, there were no crowds there, just a nice, topless beach , and three huge swimming pools (or more). The resort was at least a mile long and I didn't even go to all of it.
