Disney Transport with an ECV

I read that the Disney buses have lifts for an ECV. Is it all buses or do you you have to wait for a special bus? Is there a way to let the buses know you’re waiting for one that can handle a ECV? Specifically interested in transport between AK Lodge and AK park, but any transport information about buses or monorail with ECV would be appreciated. Thank you!

All buses have foldout ramps in the “exit” doors, half way back on the side. Most of the loading queues have a special area, with a wheel chair symbol, for you to wait.

Great info- thanks!

Just keep in mind each bus can only take 2 or 3? ECV’s if it is busy you may have to wait a bus or two.
