Yeah, I could see a couple pre-show rooms for this just to keep capacity up in the case of people missing their return times. Use them to stack a couple shows worth of guests so they aren't "in line". If the first pre-show starts to thin out, they can have the return time kiosk kick out a few immediate ride time tickets to fill it back up. The question will be how it handles the return windows, and how well the system deals with breakdowns or other delays. It could be that they keep the virtual queue below capacity and use the same idea with immediate return times to mimic a standby queue. Runs the risk of pissing people off though if they have a later return time and someone else walks up and gets right on.
