This is one area I'm a little unclear as we use our credit card for pretty much everything (airline miles). There are four of us traveling. We'll spend a few days at WDW before our 7 day cruise. I know we need cash for tips (valet at WDW and room service on ship), laundry money but what else? Taxi's if we do shore excusions on our own? How much to take for that? What about shopping in Grand Cayman and Cozemel? Anything else? Any insite on what you did would be a great help. Thanks!
