Everyone has their favorite way to deal with cash. Travelers checks are generally accepted, credit cards are used in most places (Am Ex less so than Vias and MC), there are several ATM machines and I recall reading on some thread here that you can even cash a personal check someplace on AC. Each has a cost, ATM fees, exchange fees, etc. I use Credit cards so I don't carry much cash I pay the fees. I also using the ATM since I often stay a month at a time. Pay their fees as well. Pick your poison.
