This is my favorite post about using Fastpass "late" or past the window:

I have read this many times and I was curious about how this is handled in the patent (especially since a patent doesn't 'allow' or 'prohibit' anything), it just describes a method or equipment for doing something.
I went to the
patent and looked for anything that might specifically address late arrivals. I didn't find anything, so if someone knows what specific part addresses late arrivals, I'd be interested. I did a search for the word 'late' and found 14 instances, most of them part of other words, like 'relate', 'calculate' , etc.
I did find a lot of language in the legal-language part of the patent like (my bold):
"having an assigned time in the future associated therewith at which time said customer may access said attraction via said at least one second queue, said media having assigned times which are determined and selected by a subsystem operatively coupled with the attraction and are issued in a chronological order; and
permitting a customer having a media to access said attraction via said second queue at said assigned time in the future."
That same language is repeated over and over.
The main parts of the patent had to do with how they determine the waiting time to put as a Fastpass return time, or as it's stated in the patent:
"assigned time in the future is varied dependent upon a changing capacity of said attraction over time. "
The Description of the invention (towards the last part of the patent) uses less legal language and talks about uses of waiting systems and how past systems didn't work because they didn't take changing capacity into account, as mentioned in this part of the Description:
"In actual practice, the capacity of an attraction may not be achievable due to a variety of factors, including number of customers, the demographics of the customers, attraction performance, the number of customer vehicles associated with the ride which are in service over time, the number of staff members available to operate the ride, safety factors, weather, etc. For example, the total number of customers in a park who may even desire to access any attraction may be much less at one time of day (such as at opening) than another time of day (such as mid-day). In addition, the capacity of an attraction may change due to a variety of circumstances. A ride may be taken out of service for a period of time or one or more "cars" or associated customer vehicles may be removed from the ride, lessening the capacity. The number of staff available to operate the ride may fluctuate during the day. If a fewer number of staff members are available, such as at a shift change, the number of patrons which may be loaded into each customer car or the number of cars which may be loaded may be reduced. When slow downs occur and customers with passes must wait in line, the time slots reserved by those customers for other attractions may expire. This not only frustrates the customers with passes, but leads to potentially empty seats on other attractions."
The Description goes on (in great detail) to describe how Disney's patented system takes all those factors into account in assigning Fastpass return times. More Fastpass times are assigned for times when the capacity of the ride is expected to be close to/more than the number of guests wanting to ride. Less Fastpasses are assigned to busy times.
If attractions always had the same capacity and the same demand, when you return with a Fastpass would make no difference.
But, it at least seems like one of the big reasons for Fastpass was trying to 'move' people from times where there was less capacity or more popularity to times when there is more capacity or less popularity.
You can see that on rides like Kali River Rapids, which are very busy during the day and the Fastpass return time may be pretty far out into the aftenoon. When you come back in the afternoon, the standby line may be 5 minutes, but I've been there when the Fastpass line is actually
longer than that (??because of later use of Fastpass and more guests accessing thru Fastpass than the system planned).
So, I can see reasons why people coming back later than their 'window' would make a difference. If only a few people are 'out of the window', it probably doesn't have much impact. But, if lots do, the conditions that the algorithm looked at in calculating return times may not match what's actually happening.
There are lots of things included in the patent; things that they
do need to use, but hope not to (like how to handle ride shutdowns and re-start from shutdowns). It also includes things they haven't used yet, but might decide to use - like charging for Fastpasses or having a Fastpass system that could assign times days out instead of hours out.
The patent is a kind of boring read, but interesting anyway.
