If there were a single rider line on X or this future 4d ride in Japan, we would see a nice reduction in wait times, There are MANY seats that are only filled by one person (when groups of 3 ride or odd groups) if we could fill these seats by the single riders we would shorten wait times! Of course there would need to be some way to have a single rider line up, it could be to the right of the front row line, the single riders would que up there and wait for instructions from the ride op when a single seat was available. Thus taking the single riders out of the general que and helping the ride achieve maximum hourly capacity. The rule for X should be NO SEAT goes empty! At 7 minutes per train cycle (load unload) One train operation, we cannot afford to have empty seats, it just kills me!
