You'd think there would be an official process for park extensions. I would expect a checklist with quantitative measurements (e.g. gate figures, queue times, temperatures) to provide consistency and fairness. For example, "if there are more than 15000 guests and at ride close one ride with a 1 hour queue, extend by 30 minutes. If more than 20000 and at ride close two or more rides have a 1 hour queue, extend by 1 hour." It actually seems like there's no process at all. It's just down to a manager on the day to decide based on their gut feeling, and nothing to back up their decisions (rightly or wrongly). Poor decisions like the ones this weekend will result in complaints and a bad taste in the mouth of everyone who was turfed out prematurely.
