Lots of restrooms have a plug in the "entry way". But I know that it's no fun sitting in the entry way of a restroom for 1/2 hour while your scooter recharges (but that's what I got, I figured, for forgetting to charge my scooter the night beforehand). And Animal Kingdom doesn't have "entry ways", since they're the only park with doors on their restrooms. But they also have the nicest spot to recharge your scooter. Pretend you're coming out the doors from the "Finding Nemo" show. On your right, along the wall, across from the restrooms (which are hardly used) is a plug. Back when the show was running, CMs would take
ECV drivers to enter there and park their scooter during the show. One time, the CM asked me if I wanted to charge my scooter during the show. Also in AK, there are some plugs in Pizzafari, so you can recharge during lunch.
