We divorced ourselves from Disney after they searched our daypacks (before terror concerns) and triumphantly pulled out a couple of apples and sandwiches. We were told to leave these in a locker and if we wanted to eat them, we had to do it right by the locker - there was one grim table there for the whole LA park! As we were reentering the park, the original gate attendant rushed in, to make sure that our packs were searched again.
Sure they wanted to be certain that the only food we were having inside was that purchased from them, but the paradox was that the only food they were offering inside were sugar bars and really bad fast food - no fruit, no nothing I'd want to put in my mouth. The divorce was sealed when we were visiting a safari a day later and our kid asked whether the animals we were watching were real - he was suspecting moving Disney mannequins.
