Mexico City
World-class food, walkable neighbourhoods, and prices that still feel like a mistake. Stay 4–6 days.
Shoulder-season Europe at half price, aurora season in the north, and the last good month in tropical Asia before the heat.
February is the sweet spot for northern lights: dark enough for the sky, milder than December for the roads. Mardi Gras also lands here or in early March.
The best street food on the planet, and a transport system that makes the chaos navigable. Stay 3–4 days, or 5 with a day trip.
