You can use your own wheelchair. Not sure about the others.
Yes. You may use your own wheelchair at all Walt Disney World theme parks. Walt Disney World Resort does not offer senior citizen discounts on tickets, Disney Resort hotels or vacation packages.
No senior discounts, but there are some membership discounts (check with AAA). You can bring a wheelchair in and make sure to bring your handicap sticker if you have one, the handicap parking is very close to the entrance.
