Cancún is used to tourists, but a little basic etiquette still goes a long way — both for how you're treated and for the place itself.

Greetings

A simple "buenos días/tardes/noches" before launching into a request is genuinely appreciated and often changes the tone of the whole interaction, even in very tourist-facing businesses.

Dress

Beachwear belongs at the beach and pool — cover up (a shirt, at minimum) when you head into town, restaurants, or archaeological sites. It's a small thing that reads as respect rather than rules-following.

Bargaining

Expected at markets like Mercado 28, not expected — and can come across poorly — in regular shops and restaurants with posted prices. Bargain with good humor, not aggression.

Photographing people

Ask before photographing individuals, especially at markets or in more local, less touristy settings. It's a basic courtesy that's easy to skip in the moment and worth not skipping.
