I've read reports that said it was even worse at Disneyland. I'm regularly amazed at how badly Disney sometimes botches things like this. I guess it's because in so many ways they just NAIL customer service, corporate synergy, etc. that the slip-ups seem so egregious.
They marketed the heck out of this thing. It was a really unique idea. And there is a huge market of Disney geeks who will glom onto anything out of the ordinary that Disney does (not saying this is a bad thing). So why would they not have predicted capacity crowds and staffed accordingly? I'm just puzzled by it...
