As I have to deal with hundreds, if not thousands of hotel guests/tourists every year, and I keep on having to assist them in trying to get their cards back that get swallowed up by ATM machines, cancel the cards, get police reports for the moneys they get scammed for, make long distance calls to banks and credit card companies, etc, I feel that cards are NOT the best option for visitors.
They may very well be for people living here, but traveller's checques are NOT the best option right now for tourists.
I have not had one single guest have a problem with checques over the years, yet they have had countless credit card and ATM problems.
