as someone who really can't afford this, i dont' like that i will be waiting longer while these people get in front of me.
if however, i could afford this ( calculate $2700 for my family of 6 for one day in the park), i would think it was wonderful. then i could spend the rest of my trip slowly enjoying the parks and smelling the roses.
i don't resent those who can afford it, or that it exists- as with everything else, you get what you pay for. look at the differences in quality from a value resort to a concierge level deluxe. you can buy the best if you are willing to.
i don't however, think that this will have a major impact on disney's bottom line, i think compared to disney's many sources of income, few enough people will chose to do this to not have a significant financial impact. i think they really are doing it to keep those who desire it happy and coming to the parks
