What does a family jet lag plan for Denver → Cancún look like?
Sample built by the calculator for 2 adults and kids aged 3 and 8, departing Jul 1 with a 2-day head start. Home bedtimes: adults 10:30 PM, kids 7:30 PM, everyone up at 6:30 AM. Times before the trip are Denver time; after arrival, Cancún time.

How do you beat jet lag from Denver to Cancún, step by step?
- Switch to destination time on board: Set devices to Cancún time and eat on its meal schedule.
- Stay awake on the plane: It is daytime at your destination; limit naps to 20–30 min.
- Bedtime on local time: Adults around 10:45 PM on night 1, reaching 10:30 PM by day 2. Wake at a fixed time even after a bad night.
- Short, early naps: Adults/older kids ≤ 20–30 min; little ones keep naps but on local time, ending by ~4 PM.
- Meals, caffeine, movement: Eat on local time, hydrate, skip alcohol, adults caffeine mornings only, outdoor activity in the light windows.
What's different about Denver → Cancún?
- Cancún does not use daylight saving time, so the gap is 1 or 2 hours depending on whether Denver is on daylight time (mid-March to early November).
- The flight is short (about 4h), so it works best as a daytime flight with snacks and activities rather than a sleep flight.
- Cancún is near the tropics, so daylight is strong and roughly 6 AM to 6–7 PM year-round. Sunglasses and shade are easy tools when the plan says to avoid light.
What should each age do?
- Babies & toddlers (0–3): keep naps on Cancún clock time and end the last nap by about 4 PM. No melatonin.
- Kids 4–8: one nap of up to 45 minutes before 2 PM on arrival day only if needed, then outdoor play in the light windows.
- Tweens & teens: naps of 20–30 minutes max, devices off an hour before bed, and morning light matters because teens resist moving earlier.
- Adults: no special steps.
