I think it bothers me too. I hardly see any families eating over at the "hidden" Picnic Area. Most theme parks don't allow outside foods or beverages to be taken in.
There's nothing like the smell of Peanut Butter, and hot Fritos Corn Chips wafting away on the breeze to tell you that there must be kids around!
I once saw some school field trip groups using the area when I was coming around by the lockers and yes, the smell almost blew me away...
Kids and Fritos...dangerous combination!
