Stupid Guest Tricks

A friend of mine wants to take his wife and two young daughters to Night of Joy at the Magic Kingdom in September. I mentioned to him that I've read comments about the out-of-control young adults who sometimes exhibit less-than-Christian behavior during NOJ. He went to a Christian concert in Mobile earlier this year and they ended up leaving early due to crowd misbehavior and bad language. Is NOJ still a less than pleasant family experience? Should he not bother driving 7 hours to WDW in the hopes of having a joyful evening of music and fellowship? Your thoughts, please. I told him I'd ask how CMs and fellow guests feel about the NOJ experience.
Thanks for any feedback.

My guess (and that's ALL it is) would be that if you are near the stages you should be fine. It's mostly around the rest of the parks that there is an issue... Kids who use churches and their outreach to go on rides at Disney, because they could care less about the concerts, they just want to go at a less crowded event.

Thanks, BW. I wasn't trying to talk them out of it, just wanted to give them a heads up. They are trying to decide whether it's worth the long drive down there just for the weekend.
