Disney have been adding new 'charging stations' where guests can recharge their mobile devices.
You can now charge your device at the Tomorrowland Arcade, the Storybook Circus FastPass distribution and in the tree stumps located next to benches near Rapunzel's Village. The charging stations near Rapunzel's Village and Storybook Circus offer both AC outlets, and USB ports.
No word on if there are plans for more locations yet.
