My wife and I love Cancun! We seriously considered moving to Cancun before settling on a move to Panama. The beaches are beautiful and it just a great place to vacation. We always like to spend a day or two on Isla Mujeres, it's more like real Mexico than "tourist Mexico" and there's some great food on the island. Be sure to try the local alcoholic delight Xtabentun. It is delightful. They do make mixed drinks with it but I love it straight.
