Individual bus, subway, or metro tickets will be around $3 (£2.40, €2,65, 20 Yuan) and are valid for one trip. There will also be day, 48-hour, and 72-hour passes if you’ll be using a lot of public transportation in one of the larger cities.
Renting a car will start around $50 a day (£40, €45, 355 Yuan), and then you’ll need to pay for tips, tolls, and gas. You can find my favorite car rental sites here. Before renting a car, make sure you understand all insurance and driver’s license requirements.
Taxi fares within city limits average a $4 starting fee (£3.20, €3,50, 28 Yuan), then around $1.25 per mile (£1, €1,10, 9.50 Yuan). Uber and Lyft are widely available in all large and most mid-size cities as more affordable alternatives to taxis.
One-way domestic flights average $200 (£160, €180, 1415 Yuan).
Amtrak trains are a chapter and more scenic way to see the country. Prices for Amtrak range from $3 (£2.40, €2,65, 20 Yuan) for local trips to $700 (£560, €620, 4950 Yuan) for cross-country journeys. You can find all of Amtrak’s routes and pricing here.
You’ve also got the relatively cheap Megabus and Greyhound bus options.
