From what I've heard, the queue over the past couple of days didn't even go through the tunnel, and essentially boarded onto the exit with disabled guests...
One can assume that the ineptitude of the staff at the current time is so bad that batchers just batch the entire load, forgetting the designated disabled guest seats and so faff and clusterbuggery commences... As a result, we see them stop using the majority of the queue and just create stupid procedures that make little to no sense...

As you can see, the tunnel and bridge parts of the queue aren't being used, and guests board via the Fastrack queue and onto the exit platform... The sheer "WHY?!" that comes from this shows how far Chessie have fallen in recent years... No other words describe this ride as pure and simply, awful... And they've made it worse...
