^ After being at Oktoberfest, I completely agree!
Some people act like a few buzzed adults at an amusement/theme park is going to be totally disruptive for the family atmosphere and ruin the entire day. Is there a chance that can happen? Yes, but I would bet that the situations are few and far between.
Now if it were like a Buffalo Bills game where everyone tail-gated and drank for several hours before entering an amusement park & then continued to drink though-out the day, I could see where it might become a problem.
Waldameer is an alcohol free park and when we were there last year for Memorial Day, the amount of obnoxious foul-mouthed teens and line-jumpers were enough for us to make an early exit. I didn't smell alcohol on any of them, but I was ready for a drink before we even left!
I really don't see adding a beer garden as ruining a family environment at any park. If anything it's going to be a cash cow and gain the park higher revenue.
For example: Mom and Dad are sitting in the beer garden enjoying a few cold beers because they don't really like doing rides & coasters. Perhaps they catch a bit of a buzz (they're staying on-site of course, so no D&D) and when the teenage kids come to them looking for money for something to eat or drink, Buzzed Daddy opens his wallet, hands them each a 50 spot and tells them to go out and have a great time!
Ya see...everyone wins in the end!!
