Another idea to get through Epcot is the pressed pennies. We bought our kids each a pressed penny book and they loved trying to find the machines in each country. It became a game to see who could find the machine. We let them pick out one of the three types of pennies at the machine. The book holds quite a few pennies so they plan to bring it back next trip to get more.
This also worked at the resorts. Anytime we went to a new resort for meals, xmas decorations, etc, the kids would look for a machine.
