luckily, we haven't had many negative experiences while visiting, and the worst that i can remember isn't as bad as most of these.
we were waiting in line for about a half hour so our kids (3 years and 6 months at the time) could meet mickey, minnie and pluto. we were down to the third ones in line, when the first ones in line went ahead for their turn, the second ones moved up to the front, but since i was fixing our daughter's minnie tutu and ears headband, we didn't immediately move (a foot forward lol). the woman behind us told her 7 or 8 year old daughter to go ahead in front of us. my husband turned to her and said excuse me, it isn't polite to cut in line. to which this woman replied, well if you weren't so busy messing with your baby's clothes and you were actually prepared, we wouldn't have to. a cm saw and sent the little girl back to her mom. after we were finished with our pictures, the mom went to her husband, who was standing next to us while we fastened the kids into the stroller, and told him to "do something". funniest thing i ever heard was her husband's response... "hell no! that's a marine corps backpack that guy's wearing. i'm not stupid enough to mess with a marine!" lol we got quite a kick out of her hubby backing off, but it was really irritating that she wanted to hurry her daughter in front of us, just to keep waiting anyway.
