Go USA

Very.
The drinking age is 21 everywhere, no exceptions.
Bars, clubs, supermarkets, even some restaurants check ID — and they won’t accept photos or foreign IDs without a passport.
Expect to show ID even if you look 40.

Because the U.S. is a giant patchwork:

• NYC, Chicago, Boston, DC, San Francisco: great metro systems
• Los Angeles, Miami, Dallas, Phoenix: cars are basically mandatory
• Anywhere rural: zero public transport

Most travellers rent a car for West Coast or national park trips.

Yes, but distances are huge.
Tips:

• Plan fuel stops in desert regions (Nevada, Arizona, Utah).
• Don’t park in sketchy areas at night.
• Expect aggressive highway drivers.
• Always have travel insurance — medical care is expensive.

Safe if you use common sense.
Most issues happen in specific neighbourhoods tourists don’t go to.
General rules:

• Don’t wander unfamiliar areas late at night.
• Use Uber/Lyft after dark.
• Keep valuables hidden.

Big cities like NYC, LA, Chicago, and Miami are full of tourists 24/7.

Yes. The U.S. is the tipping capital of Earth.
Standard:

• Restaurants: 18–20%
• Bars: $1–2 per drink
• Taxis/Uber: 10–15%
• Salons/spas: 15–20%

Servers rely heavily on tips — it’s part of the culture.

It’s easy but pricey.
Options:

• eSIMs like Airalo
• Local carriers (AT&T, Verizon, T-Mobile)
• Airport kiosks or major malls

Coverage is excellent in cities but patchy in rural areas and national parks.
