I've used the ones at Coronado Springs, Board Walk and Yacht Club. You will also find them at the Grand Floridian and, I think, the Contemporary. Dunno about the AKL.
The BC and BW also have those kiosk/terminal things near the public phone/restroom area...they're okay, but unreliable, and it's easy to waste time and money on them, just getting them to work right.
FWIW: there is also a Kinko's off property, on 535, not far from Steak n' Shake (mmmmm....) if you want to log on for a longer period of time and not pay the exhorbitant Disney prices.
