Outside of people at home seeing the crowds on busy days and deciding not to go, what would the value of it be?
Much more important to the park, what benefit would it get out of it?
That
would be the value of it: to the park and its employees, and to visitors.
Scheduling is a nightmare in any customer-drive business. Moreso in a business subject to changing customer counts because of the vagaries of weather.
I work for a company that is the third largest in its industry in the US, and breathing down the neck of #2. It's an industry used by every single person in the US. A few years ago they purchased a nationally-known competitor specifically because of their superior computer systems, and now they're rolling it out to all banners, so that the parent company has unity across all its stores.
"Customers make appointments", as they told us when we were dreading the change. Even though it doesn't seem obvious in a business where anyone can walk through the door at any time, they do. Our auto-scheduling system takes in an amazing amount of fine-grained data and compares the previous four years' worth of sales data against all available variables.
It would be nice for visitors if the park scheduled for 26k through the turnstiles and only 3k showed up, and nobody got sent home, but that's not a business reality. For the park, it's a disaster if they schedule for 5k and 20k show up.
