I'm pooh sized, have flat feet, and an odd stride that makes me walk ever so slightly on the inside of my feet. (I had a fairly common problem that children have concerning having legs twisted from the hips. I was a late walker, and had to wear braces as a toddler, and was extremely pigeon toed. I ran for the 1st time in grade school, and almost repeatedly fell over learning to march and play a band instrument. High mark time was awful. )
Walking at Disney for me quickly goes from carefree to slightly uncomfortable, to excrutiatingly painful. I have considered using a
ECV, but have always had an attitude that my weight would not stop me from doing anything that I want to do so I walk. I'm writing this to say that if motivated, a pooh sized person can walk at Disney even in the most trying circumstances.
Until visiting WDW with another pooh sized friend, I assumed that all pooh sized people like me walked around WDW in excruciating pain. I was amazed that my friend had no foot issues at all.
Over several trips, I have learned several tips that help. My feet still hurt by the end of the trip, but I can usually make it through most of the 1st day pain free, and with very manageable pain for the first 3 or 4 days.
After my last trip, I re-ran some of the movements using the maps from above. On our 1st day that included roaming the Atlanta airport I clocked over 5 miles, and for my other days I clocked in at between 3 and 4 miles per day. I had not been in any walking regimen, although I am now.
I know that for the walkers, this will seem like I saw next to nothing. However, over 5 or 6 days, I always tend to see everything I want to see. I like to do everything so I do attend shows and they do give your feet a chance to cool down. (I do go in the low season, and carefully plan around crowds when possible.) I start out great on the 1st day, and progress downwards from there. Towards the end of my trips it always seems like my journeys are almost from this set of benches to that set of benches, etc. My feet hurt a lot, and friends and family wonder how I can be enjoying anything.
I will suggest that you make sure that your friend has good walking shoes. My best experience has been with shoes that are broken in, but still quite new. The socks are much more important. I have several pairs of running socks with extra thickness around the heels and the fleshy part right before the toes. These are expensive. I've also found that wearing 2 pairs of thin cotton socks also helps if not wearing the runners socks. DO NOT WEAR 2 PAIRS OF RUNNERS SOCKS AT THE SAME TIME!! Never let your feet get sweaty. I have also found that rubbing your feet with muscle cream every evening is a life saver, as well as drinking plenty of water, and taking a morning aspirin for pain relief. (Do not take Aleve as it will make you retain water.)
It may work well for your friend to take these precautions and walk it for the first couple of days, and then rent a
scooter. I personally wouldn't want to be in a group that walked 12 miles per day as I would always be running to catch up to the point of being out of breath, and my feet would not be able to handle it. DH and I also stay at the BWV and I have not ever seriously considered walking to the studios. We walk to or from Epcot about 50% of the time. It kind of depends on where the boat is at the time, and just how bad my feet hurt. Waiting for the bus from MK back to the resort late at night is the worst and almost unbearable. On my next to last trip, I think I did start slowing my party down on about the 4th day. That would be a good day for a scooter. I'm sure a pool or spa day or non-commando touring in the middle would make this much more bearable.
Frankly, I hope you do not discourage your friend from going to the happiest place on earth. It is something everyone should see. If your friend stands all day, she knows if her feet hurt or not. She is also very used to putting up with whatever pain her feet go through. Scooters are readily available to those who need them. A walking regimen helps too.
I know people frown upon the pooh sized for needing the scooters, and that is imho really unfortunate. I have never been in anyone else's shoes, but I do wonder if those that would criticize the pooh sized would be willing to put their feet through torture without ever complaining that their feet hurt. I am 39 years old, and until recently assumed that my foot problem was 100% related to my weight, even with my childhood problems, and suffered in silence.
I understand that ultimately my weight is my choice, but would like for others to understand that when I am sitting on that park bench it is not because I am lazy, but because my feet are purple, swollen, and feel like they are broken.
