I did a couple of times. Did no good.
It never does do any good, I've yelled at people for using flash before they just pretend to not hear you. Cast don't care either, they're not really allowed to confront guests to tell them to cut it out. It's guest entitlement mentality at its finest. On the bright side, those pictures are going to be pretty terrible. It's the worst to have a ride ruined like that.
