My 14 YO daughter is leaving next week for a three week student exchange to Germany. My question is: what is the best way to handle her spending money? One of the parents suggested using a pre-paid visa card. I've only been out of the country a handful of times, and not recently. I do recall that using a credit/debit card (she has neither) was the best way at the time and that it always gave you the best and/or most current exchange rate???
