We just returned from a week at WDW. With all the walking, my kids (7 & 4) were quick to complain and want to stop. I spotted a colored piece of concrete and said "Look, there's a charging pod!" I jumped on it and said "Charging".
For the rest of the trip, my kids kept stepping on "charging pods" to give them more energy.
