**per the OP, these things don't ruin a minute of my trip....but they do irritate me

And thanks to whomever resurrected this thread.
1. Melted Mickey Bar remnants on the ground. I mean--if you drop the entire thing....please don't leave it there. At least attempt to try and clean it up.
2. People that are inconsiderate of those in wheel chairs/
ECV's. They (and strollers) get a bum rap due to inconsiderate operators...but I've seen so many times folks waltz right in front of one and then get shocked when they are truly accidentally bumped. You wouldn't pull in front of a car like that on the highway--but for some reason...pedestrians feel they have the right of way at Disney and will willy nilly cut off someone.
3. People who let their kids pee in line. (only saw it once at DLP and the woman hoisted her pre-schooler onto a planter and let him drop trousers and water the bushes. Ewwwww!)
4. Lengthy potty lines. But that's a problem in any major crowded venue for a women's bathroom.
5. "This area is being refurbished for your future enjoyment"--I don't know--but those signs partly crack me up and partly irritate me. I think it's the Disney-speak.
6. People that dress like they are on their way to work at the "bar". Seriously? Is it really comfy to dress like that?
7. That the People Mover is faster and that Space Mountain no longer glows while riding through it. All they need is a crazy movie on the wall and they can rename it the Willy Wonka Ride--scary scary! In the meantime--fast fast fast and pitch black dark.
8. High cost of parking--never really understood that at any venue that charges for admission. No idea how the increase in fees correlates with inflation. Is it really that much more price to operate asphalt?
9. Jerks like the jerk that literally cut me off to race to get in line for Dumbo so his precocious snowflake would get on "first". Yes--he bumped me, the pregnant lady and her 3 children...who were just about to queue, to get his butt in line. Good grief. It's Dumbo--not life saving surgery. And yes--I still consider it cutting since you felt the need to play defensive tackle to beat us in line by seconds.
