They, surprisingly, have more capacity than you think. For example, in Paris-
RC Racer- 750~800 guests/hour (9,000-9,600/day)
Slinky Dog Zig Zag Spin- 1530 guests/hour (18,360/day)
Toy Soldiers Parachute Drop- 1440 guests/hour (17,280)
While their Studio Tram Tour: Behind the Magic offers 2016 guests/hour. (24,192/day)
LMA has capacity of 5,000/show- which it never fills- but that would be 15,000 for their 3 daily shows.
So based on a 12 hr day- TSPL offers capacity of 45,240 guests a day, while the current LMA is only 15,000- but with the old tour was 39,192 guests/day.
If you actually did 4 tracks of RC Racer (which is kind of nuts- 2 would be plenty)- that's an
additional 28,800- which almost doubles the capacity of the former LMA + BLT.
Again- thats
just TSPL. TSPL cost less than $80 million too. Why it hasn't been built yet, I have no idea.
Lets pretend your cars dark ride is on par with fantasyland's little mermaid which daily capacity is 27,720. Mater's Junkyard Jamboree is 7,560. Laugh Floor has a daily capacity of 12,600. And 7DMT (your door coaster equivalent) is 20,790. And I'm not including moving Finding Nemo- which you added in your following post.
So with a clone of TSPL, A Cars Dark ride, Laugh Floor Relocate, Mater's, and a D door coaster- your capacity skyrockets from 39,192 (really, 15,000 because BLT doesnt exist anymore) to 86,190. Thats just the attractions- not even including the restaurants or shops.
4 flat rides, 2 restaurants (1 of which is simply rethemed i'd assume), 1 show (not even 2), and 2 new rides would be huge. If we see that much in one reveal, I'll be completely shocked. Have they ever revealed so much in one time? Even Avatar isn't going to have near that amount 2 new rides and maybe a restaurant. Hell- did Animal Kingdom even have that much in 98?
So like I originally said, I'd be thrilled. And yes, it would be amazing.
ETA- I think they should open TSPL yesterday. The day the extra TSMM track opens, TSPL should open up next to it. I hope this is the plan.
And any door coaster should be 42" or smaller.
