Except there are 4 "cockpits". That's a ridiculous amount of expense, again for about 10% of the visitors to appreciate. This isn't like Mickey, where they hide the fact there are 3 so the 7 year olds that still believe in Santa Claus don't find out there are 3.
The Millennium Falcon doesn't have a 3 hour long hallway you have to walk through to get to it. And you will see the one sitting outside, so even if you walk up a ramp into it, you'll know it isn't the one you saw outside. That just seems ridiculously complex to fool 30 & 40 years olds in Jedi outfits.
You could just as easily have a bunch of splits in the hallway/queue to batteries of stationary pods. If the pods move , their movements will be much less intense, and comfortable, More like Spider-Man, not Star Tours. And 25% of capacity will disappear when something breaks.
We'll see, if you go though the entire Falcon, seemlessly into the cockpit, that would be cool, just seems it will create massive technical costs. And what happened to the group of people that entered the cockpit before you? Where is the line when you leave the cockpit? The illusion had to end somewhere.
