Which one should I get for a 3 day vacation? I pretty much figured I'll carry half my money in cash and the other half on the card. I rather not have to carry wads of money but I don't have a debit or a credit card. But I'm looking for something that can be used to buy food, go to restaurants, maybe gift shopping, etc. So which one is better? Even if I don't spend it all on vacation, I figure I can use it for Christmas shopping or something.
