A simple, chronological checklist so nothing falls through the cracks. Print this, work through it, and you'll land in Cancun relaxed and ready.
18–10 weeks out
Book flights (the 6–10 week window is the domestic sweet spot). Lock in the resort — especially for peak season. Book the airport transfer. Buy travel insurance (especially June–October).
24–6 weeks out
Book tours (Chichén Itzá, Xcaret, catamaran). Request connecting rooms / high floor / quiet section. Pre-book spa treatments and dinner reservations at resort à la carte restaurants. Renew passports (must be valid 6+ months past return).
31–2 weeks out
Notify your bank & credit cards of travel. Download offline maps. Check phone plan / buy eSIM. Confirm airport transfer pickup time. Print confirmations and emergency contacts.
448 hours out
Online check-in for flights. Pack reef-safe sunscreen, bug spray, electrolyte packets, floaties for kids, and any meds in original packaging. Confirm transfer driver contact. Set phone to airplane mode until landing to avoid roaming.
5Landing at CUN
Have your customs form ready (often digital now). Walk briskly past the timeshare desks in arrivals — do NOT stop at any 'information' desk. Exit through the sliding doors and find your pre-booked driver with your name in the meeting area.
6Don't forget
Reef-safe sunscreen (Mexican law for many parks), small USD bills for tips, a refillable water bottle, earplugs for spring break weeks, and your travel advisor's number saved offline in case anything goes sideways.
Frequently asked questions
What documents do I need to travel to Cancun?
A valid passport (6+ months past return date). No visa required for US/CA tourists up to 180 days. You'll fill out a digital customs form (FMM is now online). Save the exit portion — you'll need it to leave.
When should I start planning a Cancun trip?
Peak season (Dec–Apr): start 3–4 months out. Shoulder season: 6–8 weeks. Last-minute is possible May–November but selection narrows fast inside 3 weeks.
