This type of thing happens everywhere. It's always a problem at GenCon, especially in the dealer hall, which is always thick with crowds and just not the place to stop yourself, your stroller, your scooter, whatever in the middle of people traffic. And yet...all. the. time. Ugh. Far too much of the GP lacks situational awareness--or they just don't care. I have no interest in MK, but I've seen the crowd pictures, and my sister's family braves it every couple years, so I've heard stories. I would absolutely lose my mind.
I'm expecting parts of UOR to be this way in early December, but as we have a number of days to enjoy the parks at our leisure, I'm hoping if a ride or area is too over-crowded one day, we can just come back at a different time on another day. I don't think it's that easy at Disney? Which would add to my frustration level by a magnitude, lol.
