We are currently in Disney and have been here since Wednesday (October 9), I am in awe of this thread. We have been to the festival almost every night and have not seen any of the behavior discussed in some of these responses. Yes people have been having fun and being a little loud, but I can only think of one person this whole week where I thought to myself "wow they need to go home" and guess what she was leaving. I have been run over this week alone by old people on jazzies, young people on jazzies, children running wild while their parents pay no attention, Brazilian tour groups, track teams and yes one person with a beer in their hand and guess what this was in every park not just the WS.
People need to remember that, yes most of the Disney's advertising on TV is targeted towards families, but not only families go to Disney. Their website has a whole section dedicated towards adults and when planning our vacation they sent us a DVD targeted towards adults and played up every restaurant/bar/party Disney offered. Disney is a business not a church, therefore their goal is to make money and this is is going to done by offering things specific for families, adults and kids to do.
Moral of the story, people need to be responsible for themselves in every day life, not just in Disney.
