ATMs and Banks
ATMs, for easy access to cash, can be found at many locations throughout Oahu, including shopping centers, convenience and grocery stores, and hotels and resorts, as well as outside most bank branches.
It's a good idea to inform your credit-card company before you travel. Otherwise, the credit-card company might put a hold on your card owing to unusual activity—not a good thing halfway through your trip. Record all your credit-card numbers—as well as the phone numbers to call if your cards are lost or stolen—in a safe place, so you're prepared should something go wrong. Both MasterCard and Visa have general numbers you can call (collect, if you're abroad) if your card is lost, but you're better off calling the number of your issuing bank, since MasterCard and Visa usually just transfer you to your bank; your bank's number is usually printed on your card.
