If you have a mobility device (things like wheelchair,
ECV, walker or rollator) you will wait in the same line as other guests. As you get close to the front door of the mansion and as you enter each room, the CM will direct you to stay toward a certain side.
As the group leaves the stretching room, you will be directed to a door and hallway that leads to the exit for boarding.
You will wait at the end of that hallway, which opens to the path guests exit after riding, until a CM comes to get you. Guests are asked there whether they can walk - they may say a short distance or may actually say how far. Whether they say or not, plan 200 feet.
Guests who can walk are directed to park their mobility device outside and then walk back up the usual exit hallway to board.
If you can't walk that far, tell the CM how far you can walk, so that they are not planning for something you can't do.
If you are returning to board after parking a mobility device, don't actually enter the room with the moving walkway until the CM tells you to.
In general, they try to slow moving walkways as much as possible , not come to a full stop. This is because most guests don't actually need it stopped, just slowed. And, stopping becomes a danger for other guests - people panic or try to get out of the ride car inside the attraction when the ride stops.
guests trying to get off has happened multiple times on different attractions, so they try to minimize coming to an actual stop as much as possible.
Because the moving walkway is moving at the same speed as the cars, it is usually much less of an issue than many people think it will be. The biggest trip points are as you are stepping on and off the moving walkway. I have seen people trip in those places when it was stopped though - probably more because it is a change in the floor surface than anything else.
We do need it stopped because we have to lift our daughter out of her wheelchair and into the ride car. There is a ADA ride car with a wider door opening, which makes it easier to get in.
We have been told by CMs that is the only ride car where they can plan to stop the moving walkway, so if you need that doom buggy or need the walkway stopped, you will need to wait for that one to come around. If they stopped it when you got on, they should stop it when you get off.
There is a CM stationed at the exit, walking the moving walkway to watch for issues. That CM should have a remote control that will slow or stop the walkway if needed. That exit area is also in view of the ride operator, stationed in a room above, so that person can also slow or stop it.
Tell each CM along the way inside the mansion if you will need the buggy stopped. Because of only stopping it on that certain car, telling the CM as you are stepping onto the walkway is too late.
But, as I mentioned, they can slow it to a crawl and can do an emergency stop if they see it is needed.
If you have a visible mobility need or have a cane, tell the CM before entering the mansion and also you enter each new area. As the guests are leaving the stretching room, don't be one of the first out - wait for the room to empty so you can be directed to the correct area.
If you follow the other guests into the usual boarding area, the walkway can be stopped in emergency, but not at request.
