Don't disagree, I don't think disney is seeing a massive fleeing from the parks due to FP+, but just hate the "you leaving the parks doesn't matter" bit people here throw at others all the time when they have legitimate complaints about changes disney has made. True that its doubtful that there is ( not yet at least, though probably at all) a mass exodus from WDW due to FP+ - however the whole, "if you leave then someone will replace you" thing gets old, and is beside the point really. If the best you can offer is that, well then Disney's 1 - 2 Billion investment in FP+ looks pretty shabby if they are just breaking even on visitors due to it.
Anyway, its beside the point, just don't know why someone can't say they aren't going because "X" without people feeling they need to jump in to defend disney. Disney is going just fine, they don't need your defense.
