Hotels do not, as a rule, exchange currency and only a few major banks will exchange foreign currency, so it is advisable to arrive with US Dollars, or exchange foreign currency at the airport upon arrival.

Most major credit cards are accepted throughout the USA, including American Express, Diners Club, MasterCard and Visa. Visitors are advised to carry at least one major credit card, as it is common to request pre-payment or a credit card imprint for hotel rooms and car hire, even when final payment is not by credit card. Be sure to check with your card issuer for current surcharge rates imposed for use of the card outside your home country. You should also inform your issuer that you are travelling for a specified period so your card is not flagged or temporarily suspended.

Bank-issued debit cards are accepted at many businesses in the US; however, using them to pay for many travel-related expenses, such as car hire and hotel rooms, often incurs a surcharge, deposit, or a hold on your account.

ATMs are widely available across the country.
