I get the problems. But travelling to another country is to research and accept that things are different. For example, if you rent a car in Argentina, they hardly have any automatic car, all stick, unless you do a special request weeks in advance. You could complain all day about rental cars ruining vacations, or you can just research ahead of time and ensure that what you’re trying to do is possible in that country. Lack of credit card in the US will cause you tons of other problems, nobody cares about debit, better come prepared.
