I have no suggestions but I would like to say Bravo to your Mom for going to WDW. My grandma is in her 80s and is in decent health but refuses to do anything, apart from going to the grocery store, claiming she is "too old" to do anything.
Thanks, jaklgreen. I cannot begin to express how excited I am to have the opportunity to take my Mom. She has given me so many magical WDW memories over the years and I am grateful to be able to give something back to her.
