How is your mom at sitting on the ground? I don't like to stand in one place for all that long and when waiting for shows or even when the line is not moving I sit on the ground (hard pavement). This is what keeps me from missing any attractions or shows. I walk daily (seven days a week) and play tennis twice a week, but with varicose veins and not the greatest circulation I am more comfortable sitting than standing. A bench would be great, but the ground beats standing for me. This does involve a lot of sitting on the hard ground, and getting back up ( a lot of up and down, but if she is in good shape maybe that's not an issue). It works for me. Interestingly enough too in many lines I am the first person to do this and then after I do it I end up seeing six or seven people after seeing me do it, do it themselves too. They all wanted to do it (I'm guessing), but didn't want to be the first one. It also requires me not being embarrassed about being the first one to sit on the ground and being OK with sitting on the ground while almost everyone else is standing. I have been doing this for the last 10 years when visiting the Orlando parks and am comfortable with it.
Like other posters have said, most of the lines move along pretty well and this wasn't necessary. I mostly on our last trip remember sitting on the ground for 15/20 minutes in the place we wanted to be for night time shows and sitting on the ground in a fairly long queue that didn't move that fast for Soar'in at Epcot. (Benches for sure are way harder to find than they used to be I have found.)
My 85 year old dad does not use a wheelchair or SUV at home, but gladly rents one for Disney parks. He won't do a rental for the whole trip, but will do it at the parks we are going to do on an upcoming trip in March. For lines that don't let an SUV go all the way, there is a transfer from an SUV to wheelchair available.
