yes -- we did witness line jumping. I saw two varieties. The overt kind where people saw an opening and just jumped the barrier...and the covert kind where one person at a time will pretend that they are meeting up with their parents (although they never actually said anything). This happened a couple of times -- and the second time, I gave the kid a death glare. I guess it worked b/c he stopped and more or less turned around.
People were bumping into my wife constantly -- mostly on POC -- but that was just the dad and his two sons...so it didn't happen on all of the lines. They were the worst.
On that note -- the illuminations fireworks are pretty good (not as good as HEA---but definitely worth watching). It's very projection heavy and does not have a lot of fireworks. We found a spot at the beginning of main street past the Mary Poppins stuff and were pleasantly watching for about 15 minutes. There was about 10 feet of space between us and the people in front of us. A tall guy (6'2" or more) and his girlfriend then walked and stopped right in front of me. As in...no less than 2 feet away. Completely blocked my view. To make matters worse, they rested their heads together which completely blocked any view I had.
Rather than tap the dude on the shoulder and ask him to move, I decided to go ultimate passive aggressive.
Yes...I played leap frog. I walked right around them and just stood right in front of them. Didn't even look back. My wife was not so bold...but luckily they must have got the message b/c they moved back and to the side fairly quickly.
