I agree... just folks making noise on the Internet. And right now Disney seems to be a good "target", so piling on is great fun.
Only time will tell if the Star Cruiser is a sucess or a flop... but I suspect worst case is some "seasons" they might have to offer some 25% discounts to select groups (AP, DVC, FL RES.... ), likly wouldn't make it to general public. But I wouldn't count on that happening, in fact I wouldn't be surprised if in a few years we say... remember when it was only $4,0000.
Also wouldn't be surprised if there aren't some other fully immersive (and exclusive to those willing to pay) experiences on the drawing boards... with four more Avatar movies coming and a similar heavily themed area of AK. Maybe not a space cruiser, but a research station on Pandora? Not nearly the fan base, but could be an interesting experience with cool vestiges of Pandora. Options are endless, if they find there is in fact a sustainable market.... for these types of "premium" experiences.
