Mexican Peso (MXN) $
Cash necessity
High — Local restaurants, transport, and markets require cash. MX$500–1,000 per day for everyday expenses.
Card acceptance
Variable. Tourist areas (Cancún, CDMX, Playa del Carmen) have good card acceptance. Local restaurants, local markets, and smaller towns are largely cash-only. Always have cash for non-tourist-area travel.
