If you want to leave the biggest cities and explore the surrounding states, renting a car is almost mandatory. The United States has an inexhaustible, highly competitive and technological supply of rental vehicles. Look for the best prices on the internet before you travel to avoid paying service fees and other costs at airport counters. As a general rule, the daily price for small cars ranges from €25 to €40, depending on the time of year. Weekly or longer rentals can run from €140 to €240, usually with unlimited mileage.
Other vehicles widely used in the US are RVs, large caravans that benefit from infrastructure spread across the country to accommodate them. As is logical, RV's are priced much higher than small utility vehicles and consume fuel in almost industrial doses.
Fuel is significantly cheaper in the United States than in most of Europe and tolls on the country's roads are rare. Most companies require the driver to be over 25 years old, have a valid driver's license and a valid credit card with a value available as a deposit. Some companies rent to drivers between the ages of 21 and 24 for an extra fee.
