Interesting results on the poll so far - 55% of you are in favor of the changes.
I think this result reflects the confluence of Disneyphiles on this board. Many people here think that Disney can do no wrong, and while I am a big fan, too, I think this is one where they are not exactly right.
I know, for example, that some of the distances at WDW make the fast-pass system hard to follow (not all of the times, but some of the time). A good example is, of course, the long dinners discussed above. That very example has happened to me.
The second example is especially relevant at Animal Kingdom, where walks and distances are very far, and where attraction experiences themselves are lengthy. Let's say you walk straight back to Expedition Everest or Kilimanjaro Safaris to get a fast-pass, you can either get whatever time it gives you, or just forget it. So, you get them. Then you go all the way back to your party at the Oasis. It is now thirty minutes later.
In the AK case, I am most likely to do that exact thing for a whole family, which in my case usually involves an elderly person who walks at whatever pace she sets, and that is our pace. I am interested in helping her with those lines, and we have every intention of making that time period. But I am also not going to break my (or her) neck to do it or make her Zig-Zag across that park to do it. And, yes, we do plan. But we also stop to see interesting things, to "smell the roses," so to speak.
So, while I understand the desire to fit the time period, I also understand what makes us sometmes VERY late. And I never see the FP lines so backed up that this lateness is a problem. Perhaps it is in the Spring Break and Christmas week seasons, but not so much at other times.
My point is that this is a nice perk that already works well. Leave it that way, and Disneyphiles should also remember that most people will read and follow the rules, but there is also a value to the customer service of allowing that flexibility (at least most of the year).
