I doubt they are doing damage. I dont think the huge fan boy will stop reading comics, going to the movies, or collecting action figures because they cant afford a couple nights at a resort. They will not stop passing on that love to friends or their children. At least I wont stop. I couldnt come close to afford this. Rather then get bitter about it and blame the brand I love so much I will get over it watching my Star Wars DVDS, reading the comics I have, or playing The Force Unleased on my Xbox 360. No damage done.
For every one or two people that are going to boycott Disney because they cant afford this get away thee will be a thousand who just say "Man I would like to go this sucks." And get right on with their lives. And those that do Boycott Disney will forget their outrage when the New Season of Mado drops or the next Marvel movie comes out.
