While we were waiting in the regular queue for DB yesterday, we noted that EVERY train had multiple empty seats on it. In many cases empty rows. I also noted that they were not assigning seats and barely pulsing the station. I feel that getting rid of the SRL was a mistake that will never allow DB to ever come close to running at full capacity. IMO the design of the train is as close to perfect as can be made. It allows single riders to use the wing seats and not have to ride shoulder to shoulder with a stranger (and lets face it, some at the park are a bit stranger then strange).
From my discussions with park employees, this system is STILL a work in progress. I think it is something that is here to stay, but may show up in a very different format in the future. I would suggest sending in your suggestions to the park. Just telling them that you hate the system because it is unfair will not get very far, but offering up suggestions as many have done here will have more of an impact.
