People haven't discussed the pavilion's second floor (above the ride entrance/exit) much, so here are some photos with descriptions.
This dining/conference area with the banquet tables is above the restaurant kitchen area. There is a presentation screen behind the curtain and a shelf for projection devices above/behind the archway. Those windows in the distance face toward the China pavilion. Ride entrance is toward the wall on the right-hand side (but behind the photographer).
Same as above, reverse angle (photographer's back is to the windows facing China).
Conference area with screen (back wall faces China).

The area in the distance is above the entrance, the area with the table/chairs is above the theater exit. Glass museum-style cases housed Norwegian artifacts.
The window on left is part of the front facade (over the theater exit), and the window in the distance overlooks the falls (most people outside don't notice this window unless they get close to the falls). Encased artifacts displayed along the wall on the right.
Windows with blue-ish trim are part of the facade, above the theater exit.

These doors lead into main areas pictured above. This is the view upon exiting the elevator (that was cleverly hidden adjacent to the theater exit on the first floor).

Exterior facade with the various windows pictured above.
There's a lot more space up there than many would think.
