The 5-Minute USA Trip Planner

If you only have five minutes, here is the absolute minimum you need to know before booking anything. Each answer links to the full guide for when you have time.

Step 1: Visa & Entry

The first question is whether you need a visa. If you hold a passport from one of the 41 Visa Waiver Program countries (UK, most of the EU, Japan, Australia, South Korea, etc.), you only need an ESTA authorization — a simple online form that costs $21 and is approved in minutes. Everyone else needs a B1/B2 visitor visa, which requires an embassy interview and takes 2-8 weeks.

  • ESTA (most international travellers): $21, apply online at least 72 hours before departure, valid for 2 years or until passport expires.
  • B1/B2 visa: $185 application fee, in-person embassy interview, 2-8 weeks processing, valid up to 10 years.
  • What to bring at the border: Passport, return ticket, proof of funds or accommodation for the first few nights.
  • Global Entry (worth it for frequent visitors): $100 for 5 years, skip all lines at customs.
Official source: Always verify the current rules directly at travel.state.gov and esta.cbp.dhs.gov. Rules change and third-party sites (including this one) can go out of date.

Step 2: Pick Your Trip Length

How long you stay determines almost everything else — which cities you can realistically visit, how much it costs, and how jet-lagged you end up. Here are the four most common trip lengths and what each one gets you.

LengthWhat you can doTypical cost pp (mid-range)
3-5 daysOne or two cities only. NYC, or SF + Vegas, or DC + Philly.$1,150-1,900
7 daysClassic East Coast (NYC/DC/Boston) or West (SF/Vegas/LA).$2,650-3,200
10-14 daysCross-country greatest hits, or one coast + national parks.$3,780-5,280
1 monthCoast to coast, 8+ states, multiple national parks.$8,500-12,000

Detailed itinerary breakdowns: 1 Week in the USA, 2 Weeks in the USA, and 1 Month in the USA.

Step 3: Estimate Your Budget

The single biggest question every planner asks. USA costs vary more than any country on Earth — a night in New Orleans can cost $95 while the same-level room in San Francisco is $280. We built a free calculator that handles all the variables.

Step 4: Choose Cities & Routes

The USA is huge — comparable in size to all of Europe. Trying to see everything on one trip is a common rookie mistake. Here are the 8 cities our readers ask about most, each with a full guide.

SouthFood, music, beaches, valueMiami, New Orleans

Step 5: Best Time to Visit

The USA has five distinct climate zones, and "best time" differs enormously by region. But across most of the country, the shoulder seasons (April-May and September-October) offer the best balance of weather, prices, and manageable crowds.

MonthCost levelWeather (general)Best for
Jan-FebCheapestCold north, warm southFlorida, Hawaii, Vegas, ski towns

Nov-DecMixedColdAvoid Thanksgiving week + Dec 20-Jan 2

Step 6: Money & Cards

The USA is almost fully cashless in most cities. You can get through a two-week trip with almost no cash — but there are three money decisions every traveller should make before arriving.

  • Get a card with zero foreign transaction fees — Wise, Revolut, Chase Sapphire. Saves 2-4% on every purchase. See best travel cards for the USA.
  • Know the tipping rules — 18-22% at restaurants, $1-2 per drink at bars, 15-20% for taxis, $3-5/day for housekeeping. See complete tipping guide.
  • Avoid airport ATMs and currency exchange bureaux — fees of 8-15%. Use in-network ATMs. See ATM tips for the USA.
  • Budget for sales tax — 4-10% added at the register, varies by state. Prices on shelves do NOT include tax.

Step 7: Safety & Insurance

The USA is generally safe for tourists — but the single biggest risk is not crime, it is medical bills. A single ER visit without insurance averages $2,600 USD. An overnight hospital stay can exceed $15,000. Travel insurance is not legally required but is the single most important purchase for a USA trip.

  • SafetyWing Nomad Insurance — from $45/month, covers medical emergencies, trip cancellation, lost luggage. Best for most travellers. Full insurance comparison.
  • Solo female travellers — the USA is safe in almost all tourist areas. See solo female travel in the USA.
  • Dial 911 for any emergency — police, fire, medical. One number nationwide.
  • Avoid tap water ONLY in very rural areas with private wells. Urban tap water is generally excellent and safe.

Step 8: What to Pack

Packing for the USA means packing for multiple climates, even on a short trip. New York in February requires a winter coat; Miami the same week is t-shirt weather. Our complete USA packing list has season-specific lists.

  • Universal plug adapter — US outlets are Type A/B, 120V. Most European/UK devices need an adapter.
  • Comfortable walking shoes — you will walk 15,000-20,000 steps per day in most cities.
  • Layers — cities are heavily air-conditioned even in summer. Restaurants can be 65°F/18°C.
  • Refillable water bottle — tap water is excellent and most cities have fountains.
  • An unlocked phone or eSIM — US tourist SIMs and eSIMs (Airalo, Mint Mobile) are far cheaper than roaming.

Frequently Asked Questions

People also ask
Can I drive in the USA with a foreign license?+
Most countries' licenses are valid in the USA for short visits (typically 30-90 days — varies by state). An International Driving Permit (IDP) is strongly recommended as a translation. Rental companies usually require the IDP plus your home license plus a credit card. Full guide: see our renting a car in the USA article.
Is it rude NOT to tip in the USA?+
Yes — very rude, and in some cases illegal for the server (who may be paid sub-minimum wage and rely on tips). Budget 18-22% at sit-down restaurants, $1-2 per drink at bars, 15-20% for taxis, and $3-5/day for hotel housekeeping. Counter-service (fast-casual, coffee shops) — tipping is optional but appreciated.
How do I get from the airport to the city?+
Varies by airport. NYC JFK: $75 flat taxi OR AirTrain+subway for $11. LA LAX: Uber/Lyft $30-50 or FlyAway bus $10. SF SFO: BART train $10 to downtown. Most major airports have public transit — always cheaper than taxis.
Can I use my credit card everywhere?+
Yes, in almost all cities. Exceptions: some food trucks, farmers markets, laundromats, and tips to small service providers (valet, bellhop). Carry $50-100 in small bills ($1s, $5s) for tips and cash-only vendors.
What if I get sick during my trip?+
Urgent care clinics (for non-life-threatening issues) cost $150-300 cash pay and are faster than ERs. For emergencies, dial 911 — but expect a bill of $2,000+ if uninsured. This is why travel insurance is essential. We cover this in detail in our USA health guide.

Frequently Asked Questions

How far in advance should I plan a USA trip?

Start 3-6 months out for best flight and hotel prices, especially for peak summer (June-August) or Christmas travel. ESTA or visa applications should be submitted at least 72 hours before departure — but apply 2-4 weeks ahead to be safe. Last-minute bookings within 2 weeks of departure typically cost 40-80% more.

What is the best month to visit the USA?

For most of the country, April-May and September-October offer the best mix of good weather, moderate crowds, and mid-range prices. Summer (June-August) is peak and most expensive. January-February are cheapest except for ski towns and Florida/Hawaii, which stay busy.

How much does a 2-week USA trip cost?

A mid-range 2-week USA trip for two people costs $6,500-9,500 USD including domestic flights between cities. Budget travellers can do it for $3,800-5,200. Use the free USA trip cost calculator for an exact estimate based on your style, season and cities.

Do I need a visa to visit the USA?

Citizens of 41 Visa Waiver Program countries (UK, most of EU, Japan, Australia, South Korea, etc.) need only a $21 ESTA authorization — no visa required. Everyone else needs a B1/B2 visitor visa, which requires an embassy interview and takes 2-8 weeks to process.

Is travel insurance required for the USA?

Not required by law, but strongly recommended. A single ER visit without insurance averages $2,600 USD and an overnight hospital stay can exceed $15,000. SafetyWing insurance costs from $45/month and covers medical emergencies, trip cancellation, and lost luggage.

Can I visit multiple US cities in one trip?

Yes — and most first-time visitors do. Common combinations: NYC + Washington DC + Boston (East Coast, 7 days), San Francisco + Las Vegas + Los Angeles + Grand Canyon (West Coast, 10 days), or an ambitious coast-to-coast 2-week trip. Budget domestic flights (Southwest, JetBlue, Delta) 4-8 weeks ahead for the best prices.

What is the #1 mistake first-time USA visitors make?

Underestimating distances. Americans drive for hours as if it's nothing — Los Angeles to San Francisco is 6 hours by car, New York to Miami is 19 hours. Always check distances before booking, and use domestic flights or Amtrak for trips over 300 miles to save full days of travel time.
