You have the right attitude. If you come down through Cancun I URGE you to spend at least one night in Playa del Carmen (Not Cancun). I know - some of you are going to boo and hiss that travelers should just "get here as fast as you can."

It doesn't seem to pay to go through Cancun for one person traveling alone - but two can make it an adventures and save some money.
