The Cancun edge

Cancun has the wider beach, the bigger flight network, and Playa is a 50 minute bus ride when you want it.

Cancun is the rare beach destination that also works as a base. The airport is one of the busiest in Latin America, the transfer to your hotel takes twenty minutes, and within two hours you can be swimming in a cenote, climbing a Mayan pyramid, snorkelling the second largest reef on the planet, or eating cochinita pibil in a downtown market for the price of a coffee elsewhere. That combination is why we keep building these comparisons and keep reaching the same conclusion.
