I have had problems with the prepaid debit cards. Will never use those again! Have used my debit cards at the cash machines with no problems but NEVER use them for shopping or dining. Have gotten the traveler's checks from AAA and also like using those, as the places I frequently stay at will cash them for me, and it's better than bringing a lot of cash, though I still bring cash in smaller bills. Will only use my credit cards in case of emergency.
