I actually went on line and ordered Disney Gift Cards for my two teenagers for $100 each for our 6 day stay last summer. They had these to use for purchases for themselves or if they wanted to buy anything for someone at home. That kept us from having an even larger bill at check out from charging things to the room. We had the Dining Plan, and at that time it included the tip so we didn't need cash for that either. I had my Mousekeeping envelopes made in advance, with a $5 bill in each of them, tucked into my passporter for each day. We used very little cash the whole week we were there, other than tips for baggage handling.
