Prices. Cheapest window of the year. The same resort can cost half its January rate.

Seaweed. Sargassum can appear on some east-facing beaches. Isla Mujeres north beach and the cenotes are the reliable backup.

The Cancun edge

Cancun gives you the same all-inclusive value plus Mayan ruins, cenotes, a real city, and world-class day trips within an hour.

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.
