And it creates very long lines in rides that very rarely had that problem before fastpass.
Not so sure that I agree, Herr Baron. Your selection of the Land as an example is very subjective and completely contrived. Hope that isn't too obtuse for ya

.
There are a number of factors that have affected the Land, so let's look at another ride: Splash Mountian.
Based on my general experiences - Worst line during peak times prior to FP - about 120 minutes. Worst line at peak times post FP - oh, about 120 minutes. And in my experience, the overall amount of time the line spends in "worst case" scenario is less than it was pre FP. FP hasn't really changed the overall complexion of the lines in worst case scenario, but it has changed the distribution of the people. Perhaps it is that distribution we should be talking about, and how good or bad it is.
You are correct in stating that FP doesn't change the overall capacity. The same number of people can still experience the ride. You will have a controlled number of FP people, and then you have the standbys. So in our 120 minute line example, you will just have fewer standby people in that line that eats up two hours of your day. The rest of the capacity is consumed by those FP people. It would be interesting to know, on any given day, how many riders of Splash Mountain are FP versus standby riders, and furthermore - if you added the amount of total time each guest spent in the standby line and compared it to how much time all riders spent in line pre FP, it would be interesting to see which scenario resulted in less time in line. I think the scenario that results in less overall time in line for a given attraction is the best one, regardless of how people are spending the time saved, be it in another line or shopping. While I'd love to see more rides, I don't have a problem with Disney trying to manage capacity as a way of addressing line issues.
Hey, from a personal POV I think FP is great because we know it's benefits AND it 's detriments and can use it to our advantage. However, I agree that we should look at things on the whole and not from a subjective personal POV. I also prefer to leave motives out of it. Too much speculation and too much weight often put on them. I happen to think that FP is a good system overall, even if there are things I don't like about it at times. Heck, Pirates rethinking of his DL trip is a perfect example. FP is seen as a benefit by guests. Maybe they have been duped, maybe not - but bottom line is that it helps to attract guests AND it allows them to utilize their time more efficiently, if they choose to use it. Granted, not all people use it and I haven't quite figured out why.
On the whole, when you consider all Splash Mountian riders in a day and add the total queue time, which system had less waiting? I think it is with the FP system, but that is just my speculation. If that speculation is correct, I don't see how FP could be viewed as a bad thing on the whole.
