BC Place had revolving doors when it had the blow up roof. It was the only way they could keep it from collapsing.
Yes, that is one place you see them. Inflatable golf domes, football fields, etc. Concordia university, Loyola campus, in Montreal set up one every winter and take it down for the summer. I have gone past many times on the commuter train, but never stopped to visit. I also pass it on bike sometimes in the summer months but the dome is gone then. I will have to see if they have any open activities this winter as an opportunity to visit.
