Traveling to United States with kids: tips, activities and where to stay

Visa rules depend on your passport, not on your children's age: most Western European, UK, Australian, Canadian, New Zealand, Irish and Japanese passport holders can enter visa-free under the Visa Waiver Program with an approved ESTA, while many other nationalities need a B-2 visitor visa. Every traveller, including infants, needs their own passport and their own authorisation. Apply for ESTA before booking non-refundable flights.

Timing drives both price and patience. July and August are US school holidays, so parks, beaches and theme parks are at their busiest and hotels charge peak rates. Late April to June and September to October give milder weather, lower room rates and shorter queues, at the cost of some school absence. Winter works for Florida, southern California, Texas and Hawaii; it does not work for Yellowstone, most of the Rockies or the northern national parks, which close roads under snow.

Budget in US dollars. Prices are shown before sales tax, which is added at checkout and varies by city and state.

Step 1: choose one coast. A first family trip usually means the Northeast (New York plus Washington, DC or Boston by train) or the West (Los Angeles or San Francisco plus a national-park loop by car). Trying to do both coasts in two weeks burns days in airports and leaves everyone tired.

Step 2: set 2-3 bases and 3-5 nights each. Fewer hotel changes means fewer packing mornings and more actual holiday. New York works well for 4-5 nights with kids; Washington, DC for 2-3; a national park for 2-3.

Step 3: decide car or no car. New York, Washington, DC, Boston, Chicago and San Francisco are workable without one, using subway, bus and train. Almost everywhere else, including national parks, beaches and suburbs, you need a rental car. Book an appropriate child seat with the rental company or bring your own.

Step 4: book the big-ticket items first. Flights, then accommodation, then any timed-entry reservations. Some national parks and popular museums use timed-entry or reservation systems in peak season, so check each park's official page before you go.

Step 5: plan each day around one anchor. A museum in the morning, a park or pool in the afternoon, an early dinner. US portions are large; one adult main plus a side often feeds two younger children.

Step 6: build in a rest day every fourth day. Jet lag hits children harder, and a slow morning prevents the meltdown that ruins the next two days.

Distances are the trap. The US is roughly the size of Europe, and a drive that looks short on a map can be four hours of highway. Use the 600 km rule: below that, driving is often easier with kids because you control the stops; above it, fly.

Car seats are required by state law, generally for children under about 8 years old or under roughly 145 cm, in the back seat. Rules differ by state, so check the state you are driving in. Taxis and rideshares are not always exempt.

Health care is expensive and travel insurance is not optional. Buy a policy that covers children, emergency treatment and, if you plan any hiking or skiing, those activities. Keep the policy number on your phone.

Tipping is expected: 18-22% at sit-down restaurants, US$1-2 per drink at a bar, 15-20% for taxis. It is not optional in practice and it is not included in the menu price.

Summer heat in the Southwest and South can be dangerous for small children; plan outdoor time before 10am and after 4pm, and carry more water than you think you need. Winter storms can cancel flights across the Midwest and Northeast, so leave a buffer day before an international flight home.

In big cities, book a hotel or apartment with a kitchenette and a separate sleeping area if you can; it cuts food costs and lets children nap properly. Suburban hotels near a train or metro line are often cheaper than downtown and still give you access. Outside cities, motels and cabin rentals near park entrances are the practical choice.

For a first trip, the strongest family stops are the ones the country page already ranks: New York for museums and Broadway, Washington, DC for free Smithsonian museums and monuments, and a national-park loop for landscape. Beaches in Florida and southern California work in winter; the Rockies and Yellowstone work in summer.
