Better question - why not? Though at times it could slow the queue down slightly, it wasn't too dramatic - well from what I saw anyway. Many people are saying how SAW is not designed for SRQ - but it would work very well when done rightly. Making a permanent queue divider in which disabled riders have the majority of the space - after all, a single rider queue only really needs enough space for 1 or 2 people to stand side-by-side. Anyway, the most part of disabled riders who will need a large amount for moving around are more likely to use the lift than the stairs.Then, as long as the staff get used to having single riders (instead of having them, taking away, bringing them back, taking them away again, etc.) then it would work. Dispatching SR to the upstairs station area is easy. Then, as long as you get a member of staff who can just pay a little bit extra attention to who they put where, there would be no need for the operator to call for SR. Just a matter of adjusting.In the end, I've been for SRQ on all rides, especially SAW, as it works so well and loads of seats are left empty.
