hey anniegirl, my husband and i were just there in January (first time) we found exchanging money is easy, so dont worry about that, most merchants or all that we did business took US$ anyway, you should problably read, on down a few posts back "credit card fraud",(very important info from "wendy and bywarren") do what you feel comfortable with, but as i state in that post we will take cash or travelers checks from now on, and let me also say that means NO MATTER WHERE WE GO, not just to AC, and as also stated earlier we CAN'T wait to go back!!!!!
