I understand that some people are upset, because they would like the MM+ money to have been spent on attractions. I get that. It appears we're getting attractions, as well, but I get the argument.
However, it occurs to me that a lot of people aren't liking the FP+ because it's taking away an advantage that they currently have on the rest of the guests. I know my family and I have always gotten five or so fastpasses in a day, so a cut down to three is a pretty big hit, especially if it's a menu-type system and we can only get one of the big rides per park per day. I don't have a use for a fastpass for fireworks or a parade, either.
However, I guess I can't see how this wouldn't result in shorter standby lines. If I can't get a fastpass for all the mountains in a day, some multiple times, and other veterans can't, either, it seems like it would shorten lines. I guess we'll all see when it happens.
It seems to me that the only people who are really going to be hurt is the people who try to do WDW on the cheap. People who spend more money have a better experience just about everywhere, including WDW, right now. Go to any sporting event and sit in a suite or club level vs. a regular seat. It's a much better experience. I don't understand why anyone thinks WDW should be different. As it is now, a lunch at Le Cellier is better than a burger either onsite or at McDonald's, so the person spending more is having a better experience. People who pay for a personal guide don't have to wait in line for anything and all because they paid more money. That's clearly a better experience. Anyone who thinks that everyone's getting the same experience at WDW now is deluding himself.
