It has been explained well enough, so no comment on what they are...
but I can't help, I have to say that anyone who is frustrated and is tempted to buy into this theory is being silly.
There is simply no way, the impact of GAD or
DVC FP's is minimal. Very few DVC FP's in a day spread out over 5 parks and xx amount of FP rides... GAD volunteers were limited and then they spread out their impact over multiple choices of things they could get (free ticket, etc.), and then they spread out their trips over months of park days (GAD pass only works one day at one park). To think that somehow there was some giant number of GAD FP's all at same resort on same day, trying to get on same ride makes no sense. Once again, relax and enjoy yourself... you are at Happiest Place On Earth, so enjoy. Yes, it's busy, yes the lines will be long, yes you may not get to do all you want.... so what? Relax and enjoy!
