Belguique Francs! by Ewingjr98
Belgique Money is called the "Franc" -- oops! I haven't been to Belgium in a few years. Belgian money is now called the Euro, and it's used by most of western Europe. I guess my Francs are collectors items now.
Money is never much of a problem in Belgium. Credit Cards are accepted everywhere, and ATMs accepting US cards are very common. The only money problem you'll have is trying to afford the luxury items -- the snails and mussels, coffee and croissants at the Grande Place, and dinner at the fancy restaurants!
