Where's the GMR/MMRR layout comparison at?
Both layouts are available on Google Image Search.
A basic rundown based on my rough back and forth, middle of the night and can't sleep estimate:
1. The vehicles load in almost the exact same spot as GMR's load.
2. The park scene is what was formerly backstage to the right of the old Marquee and tunnel.
3. The tunnel scene is approximately where Singin' in the Rain through Mary Poppins were.
4. The stampede scene takes up the space approximately halfway between where the Marry Poppins and Gangster scene were.
5. Goofy's engine bypass tunnel is approximately where the first part of the Gangster scene was.
6. The carnival scene is approximately where Footlight Parade and half of the Western scene were.
7. The tornado scene is where the Bank Robbery and first part of Alien were.
8. The waterfall scene is where Alien was.
Up to this point, the ride path is similar to GMR's, though it's important to note that the entire interior was gutted completely except the wall to the left of the loading area so this doesn't mean much. After this, it does not follow any sort of similar path.
9. The sewer scene - approximate location of Casablanca
10. The big city scene - Fantasia
11. The dance studio - first half of Munchkinland
12. Area between dance studio and factory - second half of Tarzan
13. Factory - Takes up what would have been all of Anubis and the first half of Tarzan, and portions of Gangster, Western, and Indiana Jones.
14. Rejoin with Goofy - Approximate location of Mummies scene.
15. Picnic - Second half of Munchinkinland, Emerald City, some of Tarzan and Mummies,
16. Unload area - Approximate location of Finale film
17. Exit theater (a recreation of the pre-show theater) - the area where the GMR vehicles would leave the finale and return to the loading dock.
So in other words there isn't really anything to go on, but you can ride and say "this is kind of sort of where
X was!"
