After reading through these, the big ones I agree with:
-Smoking in lines. There's kids everywhere and you KNOW you can't do it, so don't give me funny looks when I stare disapprovingly of you tapping cigarette ash all over 5 year olds in line for Peter Pan!
-The ECVs, wheelchairs and strollers. I say this, but when we go soon our group will have both (for an infant and my mom with a broken hip, so my thoughts may change after this or get worse!)
-The pushy parents who want everything for *their* kid, nevermind if they run over yours in the process. Definitely had many stories similar to others on here. My favorite is the moms during the parades who do the "Excuse me, excuse me were trying to get to someone" thing to everyone all sugary sweet like they're trying to get to the rest of their family and happily plop down front and center for a parade after squeezing past everyone.
My worst moment was in Disneyland a few years ago. The tram ride from parking to the gates, it had been raining and the end seats were wet. Tram was almost full and a CM told us to get in next to a large (size of group AND girth of group) family. They filled the row in front of us and their mom was in the row we were told to get in. I smiled and asked her if she could scoot down. (sucked to get wet, but everyone else in other rows had to do the same) She flat out said no, it's wet. I told her the CM said to get in and she needed to scoot. She said "not my problem" her family all laughed. My mom called over the CM who apologized about the water and asked her to move down. She wouldn't budge. I gave up and forced my way OVER her to the end of the row, sat right in the puddle, my mom did the same leaving my husband and dad on her other side. We spent the 5-10 minute ride with her whole family turned around facing us, cursing at us and yelling at us to "go to hell" for trying to make their sweet mother (sweet mothers don't say what this lady started spitting out at us when the tram was moving!) get soaked. I'm on the end, in a puddle, wet, getting yelled at by this psycho because SHE wouldn't move. When we unloaded, her family threatened us, collectively gave us the finger and thumped off. What a magical start to our day
