The United States is less a country than a continent of them — a sweep of world cities, wild landscapes and cultures running from Atlantic to Pacific. New York is the essential first hit: the densest, most electric city in the country, where a hundred nationalities stack onto one island of skyscrapers, the food and art and music never stop, and the energy is like nowhere else on earth. Fast, expensive and endlessly stimulating — the city the movies taught you to love before you ever arrived.
What things cost: New York is one of the most expensive cities in the world — hotels especially, plus a tipping culture (18–20%) and sales tax added at the till that inflate every price. But street food, the subway, the pay-what-you-wish museums and the parks cost little. When a zone below says 'low', that means low for Manhattan, which is still dear.
