what currency or credit card would you use?
I traveled to california a few years ago and had trouble with travelers checks. I was wondering, what your suggestions would be of what currency or credit cards you would carry, both in the US, EUROPE and SOUTH AMERICA, so as not to be stranded without resources. would you carry one each of visa and master card? prepaid debit card? I am thinking of doing some traveling this winter and just wanted to know, from others experience what worked best.
