Hello mprevo, we hope you find Belize as wonderful as we have.... US dollars are accepted throughout the Country.... Credit Cards (Master/VISA) are accepted at most established businesses, however sometimes the machines do not work with our intermittent internet. Therefore, I would recommend bringing a combination of Cash & Cards. We do have a few ATM machines here that will remit Belize currency and that is typically the change you'll receive when using your US dollars for purchases. No need to exchange money. If you share what area of the island you are staying on some of us can offer more 'laid back' activities that are close to you without a lot of effort or planning. Hope you enjoy your visit to our little piece of sand in the sea.
