Ok my turn. I have visited every year with my son. When either of us had to go to the bathroom, we had to go to the end of the line. If we needed a drink we got it before we got in line. If we needed a fast pass, we both went and got fast passes before we got into the line. Everyone feels that they should get special treatment because they 1) have kids or 2) because they paid to go there. Wrong. Just because you have kids does not make you special. I hate when you go to any shopping center now and they have "special" parking for parents with small children. I will tell you now that I park there because at one time I did have a small child. I think it is riduculous. The other point, everyone at the park paid to get in so why does some people think they are more privileged that they could come and go in the line. The one thing about disney is that they make it so it is very difficult to join a party who has been in line. We just got back and almost had a fistfight. It was after the fireworks at MK. Everyone waiting to get on the tram. We get in a line. While waiting we found out that a family had decided to get into two lines and then decided to get into one. Well, my feet are killing me, I could just about stand anymore and I finally said something that maybe we should just stand back and let everyone in that line come into ours. Well the "family" (and it was big) did not like the remark but it stopped the remainder from getting into our line.
There is no excuse for line cutting whether you have to go to bathroom, get something to drink, need to sit down, etc. If one party is not ready to enter the line then the remainder of the family should find a place to sit until they could all get into the line together. And to let everyone know, my son who is very tall takes big strides when he walks, me being more short and pooh build can't keep up with him. When he gets to a line, he has to wait for me to catch up then we get into line.

But if you are a parent whose child (using my own definition of child here - 13 & under - not Disney's) needs a potty break, please feel free. 
I'm nice, I mean it. I buy other people's kids ice cream, I give out stickers and bubbles, I'll guard your stuff for you while you run into a store, neighbors trust me with their kids and pets..
Nice lady. I just won't let people past me in line. I mean, how am I going to tell my DD8 who has never skipped a soul in her life that that's just not how it should work for other people?
