I am going on a trip to Costa Rica in about a month, and I was wondering what type of money do they use? Is there money worth a lot less than Canadian money? And when I convert my money into theirs do I change it from U.S money or can I change it from Canadian money? Or do I even need to convert my money, can they take U.S/Canadian money?

Hey everyone! I am in mexico and wanting to visit Costa Rica, so I am wondering what type of legal papers I will need, in order to go there?
