Me and my girlfriend will be backpacking around SEA/South America for the next 2-3 years, I am extremely stressed while trying to look at credit cards to get. Does anyone have any experience with credit cards that work well to use while travelling on low budget? Maybe cards that have no cash withdrawal fees or discounts when booking hotels/flights? Also it would be a great plus if they have a good app that makes it easy to keep track of your money.
