Are we sure that only one bench per car can fold? I thought I heard that all of the benches were hinged, though of course if there are any folks on board who walk onto the gondola, at least one bench has to be down to give them a place to sit, because they are not going to be allowing standing riders.
If both benches are hinged, one could in theory accommodate 2 wheelchairs or
ECV's, but their users would have to be the only passengers in the car. I think that one gondola can probably handle 2 single strollers easily with one bench up, but 2 doubles might be pushing the limit, and would almost surely have to unload on the stationary loop, because there probably wouldn't be room to turn them inside the gondola.
