Sorry to hear that some of you had bad times. Just out of curiosity, what night did you go? I know that Saturday night was way more crowded than Friday. I'm over in Where Evil Hides, and Friday night the line was only twenty minutes or so, but it sure looked a lot longer on Saturday as I was passing through.
As for it being a bad experience...
I hope that you go back before the end of the month. I know that on opening weekend there're still a few kinks to work out. Trust me, I know. And it sucks that you paid your money to get what may not ultimately be the full experience. Hopefully this past weekend won't sour you to trying it again this month, once everything is in full swing.
(And just to play devil's advocate to myself, I know that "Give it another chance" might sound lame since you spent sixty bucks a pop to get in, and I'm not trying to make excuses or anything. I'm just sayin' is all.)
