It’s not that bad. Lol. We aren’t talking a Walmart on Black Friday scene.
The year Toy Story Land opened, Hollywood studios actually was like that, because the way they were initially doing FP with only one toy story ride eligible, everyone wanted to rope drop the rides they couldn't get FP for. We got there super early and were at the very very front actually touching the rope. I'd estimate by the time they dropped the rope (which was a literal thing back then) were there were several thousand people behind us crammed in shoulder to shoulder-it was a sea of people all down the street as far as the eye could see. When they started moving everyone broke into a run, and a teenager literally
vaulted off of our stroller, almost knocking it over with our child inside, my husband had to pick up our then-7 year olds because people were shoving them and we were actually scared they might get trampled. Came here and posted right away to warn others and half the people were skeptical and thought I was exaggerating, and half were like "yes, that happened to us too and it is a mad house and they need to so something before someone gets seriously hurt."
Every other park at rope drop was much more civilized. We did enjoy the castle show at MK but no more so than the other little castle shows they used to have throughout the day.
I really think rope drop is no big loss. It's so much easier to just arrive and go straight to whatever you want to ride--it spreads out the crowds instantaneously. Only downside is it is somewhat confusing what is open before official opening time and CMs won't give you a straight answer. Thank goodness for disboards.
One more thing to add: Disney has announced that sometime this year (likely closer to 50th anniversary) they are going to give on-site resort guests 30 minutes early access to all four parks, every day. I think that suggest to me rope drop is a thing of the past. It'll just be resort guests entering early, then everyone else waiting outside the park gates (or at MK, the hub like they used to do for EMH).
