This actually solves a lot of problems and I would bet a years salary that HFE will move to this in the next 1-3 years. Here are my initial thoughts:
Think of operating days like a basketball game, or concert- with demand base pricing Silver Dollar City could know how many people have pre purchased for any given day. Currently you can purchase a ticket today, and not use it until Christmas. This is why you see understaffing on unexpected busy days. Sure folks could still buy day of, but you would know your bulk attendance (80% of people buy online) before you open your gates.
"Nothing was open"- days like Spring break and other limited operating days would now be "discounted" to get those who gripe about those things less to gripe about.
Holidays are too busy- now they will be less busy because more people will visit on less busier days because it's less expensive evening out attendance.
I look forward to this day!
