From what I have heard it sounds like they are expecting up to 200,000 people to show up opening day with park capacity being about 75,000... The Millenium Falcon attraction has a rumoured capacity of 1,800/hr which is right in the middle (lines up with Indy while being higher than Star Tours, Matterhorn, and the subs). I was reading yesterday that Rise of the Resistance is a 28-minute ride experience. That is just going to kill the queue when it breaks down as people will be held in "chunks".I've been hearing horror stories about what Galaxy's Edge will be like when it opens at Disneyland in particular. The capacity on the Falcon attraction is an absolute JOKE and should have never been greenlit with a number that low. Word on the street is in the testing phase they're having a hard time keeping Rise of the Resistance operational for even a full hour at a time due to the complex ride system. Far and away the biggest draw dining wise in the cantina will literally only be able to accommodate about 1/50th of the crowds in any given day assuming people want to actually stay in there for any extended period of time. Apparently the park is having a really rough time even finding CMs to apply for Galaxy's Edge positions, and most of the old-timers are avoiding working there like the plague. I'm sure it will be an immersive experience on paper just walking around the land, but it seems like Disney is having a really tough time getting the pieces to fall into place for an opening season that even remotely resembles "smooth".
SW:GE is going to absolutely cripple the park until Marvel Land opens in DCA.
