I need someone's help. I have been planning a trip to Costa Rica for months. I have made our hotel reservations and today I got my AmEx bill. We reserved a room at the Mango Moon at MA. I understood that they would bill me for one night in advance. That's fine. I also understood the rate to be $250 but my AmEx says $601.11. Is there some currency thing I don't understand? I can't afford a hotel at that rate! I did a currency exchange thing online with colones and that came up way less. So I don't know what might be up with this. I'm freaking out!! Will someone tell me please, when you see hotel rates online are those American dollars??
