Getting There
CUN is a major hub — direct flights from most big US cities in 2–4 hours, and direct from the UK in 10 if you're committed. Book airport transfers through the hotel; the taxi situation at arrivals is a gauntlet of clipboards.
Where To Stay
The Hotel Zone is a 20km sandbar of resorts. Party end is around km 9 (Coco Bongo territory); family-and-couples territory spreads out from there. Check where your hotel actually sits before booking — "Hotel Zone" covers a lot of very different holidays.
All-inclusive maths works if you drink like a group of you. Do the maths anyway; the top-shelf stuff is usually excluded.
Nightlife
Coco Bongo is the famous one — half nightclub, half circus, worth doing once. Open-bar covers ($60–80) are standard and genuinely open.
Everything big is ticketed and promoted hard. Buy from official sites or the hotel desk, not the guy on the beach with a laminated sheet.
Day Trips
This is where Cancun beats every European party beach: cenotes, Chichén Itzá, Isla Mujeres by catamaran, Tulum if you fancy paying triple for the same beach with better Instagram lighting.
The catamaran to Isla Mujeres is the best group day out. Book the ones with capped numbers unless you want a floating queue.
Costs & Safety
The resort bubble is safe and heavily patrolled. Use common sense beyond it: registered taxis or hotel transport at night, no wandering off the tourist grid at 3am, and don't buy anything illegal — the people selling it are not your mates.
Scam-wise: timeshare pitches dressed as "free breakfasts", dodgy currency conversion (always pay in pesos), and beach vendors' opening prices are a comedy routine. Haggle or walk.
The Singles Scene
Peak social energy, especially during spring break — pool parties and open bars do the introductions for you. Big international mix, everyone's in holiday mode. Same rules as everywhere: be fun, be respectful, and the resort security has seen every version of not-respectful.
The 40+ Verdict
Great, honestly — just book the adults-only resort at the quiet end, do the cenotes and the catamaran, and visit the party zone on your own terms. Cancun scales to your energy level better than any European strip.
