I am planning a trip to London and Paris next summer. I have been doing some research on the best way to convert any money that I will be taking with me. Some friends who travel a lot have mentioned gettign a Currency Card where I preload the card with money and then it will convert the money for me and then I can use it to make purchases and also to withdraw cash from ATM's. I visited a couple of sites who offer the card and I am still unsure. Has anyone ever used one of these cards? Any help would be greatly appricated.
