It wasn't the cast members....for the most part, they were great.
It wasn't the attractions....everything was running smoothly(except for POTC on Saturday night, and the MSEP stalling for a good 15 minutes that same night)
It wasn't the Magic Bands....they worked perfectly
It wasn't FastPass+....I thought it worked pretty well for us, no real complaints there
It wasn't the bus transportation....they ran pretty steadily, even if the lines were a bit long for my liking
It wasn't the food....It was hit-or-miss, but primarily hits
It was the other guests. Not all of them, of course, or even a majority. But the most negative part of our week at WDW was the behavior of some of the other park guests. And this isn't your "massive international tour group"-type story. Didn't see a single one of those all week, actually.
This includes....
-A family who walked beside us all the way out to the bus stop at MK. When they reached the edge of the bus stop canopy, they found an empty wheelchair. At that point, the dad, who had walked with no limp and actually was carrying one of his daughters on his shoulders, sat in the chair and was wheeled to the front of the bus line by his wife, then faked a limp while he hopped onto the bus. We saw the entire thing. And so did someone else on the bus, who saw that same family pull the same maneuver at BTMR earlier in the day.
-Two ladies who threw a tantrum because they weren't allowed to sit in the wheelchair section at the Frozen show at DHS, even though neither of them was in a wheelchair. The CM stood firm and explained that it was for wheelchair parties only, but these two wouldn't stop raising their voices until another CM finally broke down and let them do it.
-More line-cutting(especially at the park entrances) than I can ever recall seeing before.
-More complaining to/about CM's than I can ever recall seeing before.
I'm usually not the "Disney Police", because I'm focused on my own experience and my family's experience. But it was over-the-top noticeable last week. If you fall into one of those categories above, just stop it. Cut it out. It's pathetic. Do things the right way. Especially the wheelchair thing....there are people who LEGITIMATELY need that access. Don't be a scam artist, don't set a bad example for your kids(who, by the way, knew their parents were scamming, and complained about it), and interfere with those who truly need the assistance.
Disney was great. Some of the guests? Not so much. Again, it was the smallest of percentages of guests. But it happened frequently(and blatantly) enough that it stayed with me the whole week.
