That kind of folding seat would not be allowed.
Some of the reason why include:
- most lines actually don't come to a stop, they keep moving along very slowly. So having a seat that needs to keep being moved along or folded/unfolded becomes an issue.
- the seat would need to be folded up at the boarding area, and then what happens to it? Do you take it on the attractions with you?
- in the case of an emergency evacuation, the seat could become a barrier to getting people out quickly.
There are 2 types of seats people have reported being able to bring in.
The first type is a cane, with a fold down seat. Because it is a cane, it is first of all, a mobility device. A cane can be helpful for people who find it painful to stand or walk because it's possible to take some weight off one hip/foot/knee at a time by leaning on the cane.
Most of those seats are easily and very quickly flipped up or down. And, the cane is either small enough to go on attractions with you or be leaned against the wall where wheelchairs are stored during rides.
The second is a kind of walker called a rollator. They are rolling walkers and have a fold down seat. So, the person can choose to use them for support when walking or fold down the seat to sit. Because they have wheels, I've even seen people walking along with them using their feet to propel themselves while seated.
Those would be left with wheelchairs on the attractions. 10 years ago, nobody was using them, but they are common enough now that we see several people with them every day.
His other choices would be a wheelchair or
ECV. Some people use them to get from place to place and only bring them into line for attractions where there will be a long wait.
