I feel that most of the time adults are the problem and at a place like Toys'R'Us or Disney it is multiplied. I think there are two issues:
1. Adults who get drunk and cause trouble or are just angry and bitter and then lash out at guests, which is terrible behavior and shouldn't happen anywhere, especially around kids!
2. Adults who use their kids as an excuse to hurt, be rude to, or terrorize other guests and that includes children as well. I mean how many times have I read on here and on other sites/reviews/stories of these so called wonderful parents pushing their kids in front of some other family all in the name of "well this place is for kids so." lol. Yeah that is BRATTY behavior, from ADULTS.
Look WDW and DL is not just for kids; it was never the intention. If it were then 99% of the land would be covered with kid friendly entertainment. It is a healthy mixture of fun for people of all ages, in my opinion. Hello, WDW the only place where kids are welcome? NO WAY. There are sooooooooo many places for kids, which is great, I guess. I hate to say it, but having a place JUST for kids is annoying to me as I feel sometimes the parents, ala adults, are forgotten. I feel for the parents that go to places that are EXCLUSIVELY for kids with cartoons going 24/7.... Parents need time too, they need some down time, or a chance to just turn off the cartoons for a sec, so to me WDW offers this, that mixture, and is for FAMILIES and ADULTS, People of ALL ages. I just feel like the whole "this place is for kids" argument is flawed as it clearly isn't.
As a teen I enjoyed WDW just as I did as a kid and I'll enjoy as an adult just as I did before. I'll do more adult entertainment, obviously, but I'll also enjoy being around kids. WHat I don't enjoy is the badly behaved, adults and kids, but that can happen anywhere.
