One thing that I found was necessary (my husband was fully confined to a wheelchair and could not even stand by himself) is to get a room with a "roll-in" shower. These are great as the person can be wheeled right in or walk right in and there is a shower seat to seat on,
This means no "mom and pop" motels any longer and rooms will be more expensive but the convenience and it taking so much less effort to bathe is well worth the money.
Always make sure that the motel that you book has an elevator and always ask for a room by the elevator; far less walking that way.
There are so many things that you can do to make life easier for her and you have to always remember that somethings just are not practical for one to try to do………..such as walking gravel paths or even trying to push a wheelchair on them. But there are still many places you can go for fun and interesting experiences. Go online before any trip and do a little research. Call restaurants ahead of time and see if they are really assessible. I could go on and on about this subject as I have been through all of it.
