Planning your first all-inclusive vacation? You’re in for a treat. But like any trip, a few common mistakes can turn a great experience into a frustrating one. Here are the ten most common errors first-time all-inclusive travelers make—and exactly how to avoid them.

1. Not Making Restaurant Reservations on Day One

You arrive at your resort, check into your room, and figure you’ll book dinner whenever. By evening, you find out every à la carte restaurant is fully booked for the next three days.

Packing for an all-inclusive vacation in Mexico should feel simple, but travelers often overthink it. The good news is that all-inclusive resorts like Sandos handle much of what you would normally pack, which means you can travel lighter and focus on what actually matters for your trip.

This guide covers everything you need to know about what to pack for Sandos resorts in Cancún, Playa del Carmen, and Cabo San Lucas — and more importantly, what you don’t need to bring because the resort already has it covered.
