Big cities have a reputation for being expensive, and hotel rates in places like London, New York or Hong Kong do nothing to change that impression. But look beyond the nightly rate and the picture flips: flights to major hubs are often cheaper than flying somewhere small, public transport can save you hundreds over a week, and cheap, genuinely good food is everywhere because locals need it too. The trick is knowing which costs to attack and which to accept.

Start with the big three: lodging, activities, and food and drink. Accommodation deserves the largest slice of your planning time, since city room and rental rates can be brutal — though affordable options do exist even in New York. After that, budget for what you'll actually do, and be honest about your drinking habits, because a cocktail with every meal quietly inflates the total.

On activities, the advice is counterintuitive: don't go cheap. Quality tours and museum visits are how you get to know a city, and rock-bottom prices usually mean crowded groups and rushed guides. Book in advance so you can budget properly rather than deciding on the ground.

Food is where the savings live. Skip anywhere aimed squarely at tourists — the food is blander and the prices higher. Instead, research your neighbourhood before you go: Reddit threads and Google Maps filtered by price tier work well. Your hotel concierge or rental host is a solid backup source. A useful shortcut: cuisines like Mexican, Chinese, Vietnamese and Indian tend to offer generous menus and daily specials at fair prices.

Transport rewards a little homework too. Subways, buses and rail lines are navigable with Google Maps, and the main hurdle is just working out how passes work — again, ask your concierge. But note that some cities, especially in the Americas (Los Angeles, Cancun, Vancouver), have weak public transit, so if you're relying on taxis there, budget for them upfront. And don't forget the airport run: that single ride can be pricey, though many major airports now have train links to the centre, which shrinks the remaining taxi fare dramatically.

Two final habits save money and stress. Watch for scams — big cities are where pickpocketing, fake tickets and overpriced bazaar deals concentrate, so treat too-good-to-be-true offers with suspicion. And practise patience. Surge pricing after a concert or a panic-bought replacement flight are exactly the impulse decisions that blow budgets; waiting an extra twenty minutes often costs nothing but time.

Who is this for? Anyone heading to a major city on a real-world budget — the framework works whether you're spending a long weekend in New York or a fortnight in Tokyo. Prioritise lodging, invest in a few good tours, eat where locals eat, ride public transport, and stay patient. The expensive reputation survives mostly because of the decisions travellers make, not the cities themselves.
