I know there is a lot of fear that FP+ is going to severely limit the number of FP a person can use in a day. Many of us are used to FP'ing 6 or more times a day under the current system. However, there have been several posts in the last few months about how bad stand-by lines have become - that FP'ers have basically "taken over". Would FP+, and it's limitations, not help ease this problem? Would stand-by lines now become quicker?
I know...no one knows the answer...but I'm trying to think positive here! Our trip is in January and I'm afraid it's still not all going to be sorted out by then
This is a GOOD question, one I have been putting a lot of thought into, but the answer I fear, is not one you will like.
While fast pass availability and usage would decrease, ride capacity would not increase. So, there are two possible outcomes... ride usage stays the same, or some people opt out of rides because they can't FP them.
In the first instance, at first glance it would seem for someone who would otherwise have rode standby their wait time will decrease. If normally while waiting in a standby line 100 people hopped on Fastpass, and got in front of them, thus increasing their wait, for every FP that is removed from the system, one less person cutting in front. However, this scenario only works if we assume a limited number of people, using the ride in a given time period, without people using the ride before or after them, like the first hour of the day in the park.
If rider usage stays the same, then even though fewer people are using FPs, those people would still be using Standby lines, which would mean, that by 12pm, or 3, or 6 .... you would have the backlog of not only Standby riders, but also the people who would have otherwise used FPs. Which means Standby times would not change. If ride Capacity does not increase, and ride demand remains the same, then wait times are unchanged.
Scenario 2, is probably the more likely, with limited FPs, there are fewer people using FP, which means that again, those people are forced into Standby, however, people will opt out of rides at a certain wait time point, which means ride usage will decrease, and therefore wait times will decrease.
In scenario 1, not much happens, except for people who currently use FPs well and plan their day well, wait longer.
In scenario 2, people do less while at Disney, because they skip rides due to lines.
You might try to envision a scenario 3, where ride usage is spread out over the whole day to make more efficient usage and decrease average wait time, and it might do so, however on the headliners, this is much less likely to be effective, since the demand is beyond the capacity for those rides.
