My wife uses a scooter too. Make sure you book an accessible room. The scooter can not be left in the hallway, it has to be kept in your room. Not all standard rooms are large enough to handle it.
You can sit in the theater in the last row. They have spaces allocated for the handicapped person and their guest. The Windjammer has tables with an accessible sign on them. If a non handicapped person is using them, just tell the head waited and he will ask them to move.
For tours, the web site indicates it it is accessible.
Ask if you have any questions.
