Budgeting for a USA Trip

Understanding the Costs of a USA Trip

The USA can be affordable or expensive depending on where you travel. Cities like New York, Los Angeles, San Francisco, and Miami tend to be pricier, while smaller cities and rural areas offer more reasonable travel costs.

Typical Daily Budget

• Budget travellers: 70 to 120 USD per day
• Mid range travellers: 150 to 250 USD per day
• Luxury travellers: 300 USD and above per day

Accommodation, domestic flights, and park entry fees can add up quickly, so planning ahead helps reduce costs.

Saving Money on Holiday in America

• Compare flight prices between cities
• Travel off peak
• Use public transport where available
• Eat at casual diners, food trucks, and markets
• Book tickets in advance
• Use an eSIM USA instead of roaming

Many travellers also take advantage of free attractions, free walking tours, and public museums.

Currency and Money Tips

The United States uses the US Dollar. Credit and debit cards are accepted almost everywhere, including small shops, cafes, and transport. Mobile payments like Apple Pay and Google Wallet are widely supported.

ATMs are common, but withdrawal fees vary by bank. Tax is not included in price tags, so your final bill will be slightly higher than the displayed cost.

Transportation in the USA

The USA is huge, so different regions require different transport strategies.

Domestic Flights

Because distances between major cities are long, most travellers use domestic flights. The USA has numerous low cost airlines and frequent daily routes.

Trains

Amtrak trains are scenic and comfortable but can be slower than flights. Popular routes include the Northeast Corridor between Boston, New York, Philadelphia, and Washington DC.

Renting a Car

Road trips are one of the most memorable ways to experience the USA. Renting a car is ideal for places like California’s Pacific Coast Highway, Utah’s national parks, or the Florida Keys.

Rideshare and Public Transport

Uber and Lyft operate in most major cities. Public transport is good in New York, D.C., Boston, Chicago, San Francisco, and Seattle.

In many other cities, rideshare apps or car rentals are more practical than buses or trains.

Safety and Pickpocketing Advice

The USA is generally safe for tourists, but every major city has areas where pickpocketing and petty theft can happen.

Common hotspots include:

• Times Square
• Hollywood Boulevard
• Miami South Beach
• Las Vegas Strip
• New Orleans French Quarter
• Chicago transit stations
• Tourist areas during festivals or events

Ten Tips to Avoid Pickpocketing in the USA

1. Keep your phone in a zipped bag rather than in your hand.
