As
@Staren said above, a knee scooter at WDW is... difficult at best. Especially if the user has not had weeks of use and practice. I could see it making things worse.
Please tell your Mom this:
Mom, I'm about your age (OK, maybe a teeny bit older - but that just means you have to listen to me! LOL) and I want you to know something really, really important. Every day, *thousands* of people pass through Walt Disney World, and lots of those folks use scooters (Disney World calls them "
ECVs") or wheelchairs that a family member pushes for them. A *large* number of those people never use a mobility device anywhere BUT at Disney World. Why?
Because at WDW, you can easily walk between 3 & 10 miles per day, on average. So, a knee scooter, or someone who is not a daily, lifetime wheelchair user at WDW quickly tires out simply because of the distances involved.
I have some health problems, too - mine just started a lot earlier in life

I have to use my personal mobility device wherever I go because my legs don't work as advertised anymore. I don't like it, but I decided a long time ago that I would rather use the mobility device and go and have fun versus staying at home and being sad.

I remember very vividly the first time I had to use an ECV at WDW. I thought I was going to die from sadness and humiliation and mortification. I wasn't handicapped!!! This was not me!!! But there we were in the parks, and I had to call a vendor to bring out an ECV because I just couldn't walk anymore.
And then a funny thing happened.
I didn't die! (Look! You can tell, because I'm right here! LOL)
And something else happened on that trip. I found that because I wasn't in pain, and limping from bench to bench, constantly stopping to rest for a moment... that our family not only moved faster, but we were having more fun! When I got back to the Resort Hotel at night, I got a good nights sleep - not tossing and turning because I was sore and swollen - and there were lots of times when *I* was ready to go, and my family was begging to stop and sit for a bit! Suddenly, they weren't waiting on me anymore, and I could go all day easily - something I had not been able to do for a while at WDW. It was one of the best trips we had had in a while. I didn't realize until then just how much my stubbornness had negatively impacted our family vacations.
I learned something else important: The people you are with - and the people around you - will take their cues from you. If you are upset and unhappy and scared and angry about using an ECV, they will be as well. If, on the other hand, you treat it as a non-event, they most likely will as well. So, get on that scooter and ride! Have a great time, and wave at everyone like the visiting Princess you are!
And think about it like this: Using an ECV is simply using the best possible available TOOL to get the most possible enjoyment from your vacation.
If you need glasses, do you refuse to wear them, going through life squinting at everyone and everything? Probably not.
If you need to use a calculator to do math, do you refuse to touch it, and instead resort to pencil and paper - or counting on toes and fingers? Probably not.
Both of those - glasses and calculators - are TOOLS that we use every day to make our lives more efficient. At WDW, many people use an ECV as a tool to improve both their stamina, and their enjoyment of the vacation, and to manage pain.
If you are worried about other peoples perceptions of you, please don't be. A lot of the people you will see using personal mobility devices and aids at WDW have a "hidden disability". Anyone who judges them does so from a place of fear and ignorance. Using an ECV to maximize your vacation at WDW is no different than using a pair of glasses to see, or a calculator to do math. It is a tool to accomplish a goal or task. Nothing more.

Prior to owning my own personal mobility device, when I visited Disney World, I always rented from outside vendors. Here's a quick rundown of why:
- The transportation system at WDW is great for folks on wheels. Nearly every single boat, and all of the buses and monorails are ECV/wheels ready. Yes, you board first, and you get off last, so it can "slow" things down a bit, but once you are experienced, you will be amazed at how quickly you can drive on/off the bus and get on with your fun!
- Renting from outside allows you to use the ECV at your Resort hotel. Some of the resorts can have quite a hike from your room to a bus stop, or to the laundry, or to dining options, etc. Every WDW Resort hotel is very wheels friendly as well as the Parks. Plus, having the ECV at the Resort meant that I could get up and go get my early morning coffee at the QS while the rest of my sleepy turtles got ready in the morning. I was *independent*, and able to go everywhere I wanted or needed to.
- Disney Springs (formerly Downtown Disney) is much larger than it used to be, and even with the new centralized bus stop and the boats running between the two far ends, you can still do a BUNCH of walking there. We absolutely love to go down there for shopping and dining, and so and ECV is a must for me there.
- Sometimes (not always) the parks run out of the rentals. During the course of the day, the inventory at any of the parks can fluctuate. You cannot reserve or hold an ECV at the Parks (or Disney Springs). You can "hop" your rental between them, but if you give up your ECV at (for example) the Magic Kingdom, and then go over to Epcot, and they are all rented out... you will have no choice but to wait until someone returns one as they are exiting the Park.
- Last, and (for me) not least is the maneuverability factor of the Park rental units. Those are larger, very heavy duty units, but as a result, they are far more difficult to maneuver around in tighter places. Some of the bathrooms are very difficult, if not impossible with those.

Remember that you can always visit the First Aid center in every one of the Parks if you need ice or to lay down and prop up for a bit.
Have a Magical trip - use the tools we have available to have the best possible trip for you and your family!
