...Except that with the ticketing system, they are allocating all 10,000 seats within two or three hours, possibly less. At the rate they were distributing tickets on Saturday morning, it would take almost five hours to distribute the tickets; the fact that they were 'sold out' by 2:00pm when I returned to the ride indicates that they either picked up the pace a bit, or deliberately undersold the ride.
In practice, it is unlikely that 10,000 people are going to arrive at the Millennium Force queue between 11:00am and 2:00pm and decide to wait. 4,000-4,500 people perhaps during that time will join the queue, depending on how long the line is at 11:00. Instead, people tend to look at the line, decide it is too long, and move on to something else, returning to the ride when the crowd has abated a bit. This happens throughout the day, and what you ultimately find is that once the ride's queues fill completely, people tend to join the queue at about the same rate that they leave the queue at the other end. A good demonstration of this is what happened to Blue Streak in 1994. Prior to 1994, people would line up for the Blue Streak until they filled the queue, and the queue began to spill out onto the midway. That line rarely ever extended beyond the Calypso, and when it did, it was about a 20-minute wait. The longest line I ever saw for the Blue Streak prior to 1994 was for an ACE ERT in 1992 when the line extended from the queue entrance and stretched halfway down the main midway.
For the 1994 season, Blue Streak was reengineered for flush-loading, and a 60-minute queue structure was constructed behind the station to replace the 10-minute queue structure located in front of the ride. Now it is not at all uncommon on busy days to see a 60-75 minute wait for the Blue Streak, simply because the queue structure can handle that many people before potential riders decide, "I'm not waiting that long to ride the Blue Streak."
The upshot of all this is that the same holds true for other rides. The lines for Cedar Point coasters, when they are running at or near capacity...particularly when they are running at greater than 1,000 PPH...will rarely spill beyond the queue structures even on busy days. Once the queue is full, most (not all) people tend to move on to another ride. So without the ticket system, you're not going to get an 8-hour queue at 11:00 in the morning. With the ticket system, people *do* have to effectively wait in an 8-hour virtual queue, and to get a ride in that 8-hour period, they must show up ("get in line") early. Without the tickets, the line's length is self-limited, and people can enter the queue at any time during the day. Why does it make any sense at all to trade a self-limiting 90-120-minute queue contained within the queue structure for a series of large mobs of pissed off people standing on the Frontier Trail?
