You can get a list of the penny/quarter machine locations at each of the parks. Be careful however, they may be out of date. Last year we got a list at MK. We went through the entire park locating the machines and getting the pennies. The list was only about 75% accurate. As we walked around, we marked it up with the up to date information and gave it back to the CM at city hall.
We still need the pennies from the Disney Institute. I know it is only open for spa treatments. Does anyone know if the penny machines are still there?
