Where Miami genuinely wins

No passport needed for Americans
Elite nightlife and dining
Easy logistics

Pick Miami if your budget is open and you specifically want what only it offers: no passport needed for americans.

What catches people out

Hotel and dining prices are steep
Water is pleasant, not Caribbean
Parking and traffic

The Cancun edge

For the price of three Miami nights you get a week in Cancun with better water and included food and drink.

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.
