That makes sense. The thought I have had is that they would have the virtual queue represented throughout the park; and then use the outdoor extended queue and the greenhouse as the primary queue--to then as you seemingly gather, bring in small groups at a time and to have TM's at the ready to make sure the flow keeps going.
Is Waterworld going to operational by the time the park reopens? That and Animal Actors are outdoor shows, and wouldn't have issues, as opposed to Special Effects Stage and DreamWorks Theater.
