Personally, I would have changed The Crypt (surprise!). I wouldn't change much, but I think a change in music and lighting and/or a (minor) change in ride cycle would have helped.
Ride Cycle and Dream is Collapsing- Dream is Collapsing (the music from Inception that plays while the ride was operating) is written in 6/4 time. This means that there are 6 beats in a measure, and quarter notes get the beat. Since it is written in moderately-paced 6/4, this allows ample time for the ride to operate.
When the ride operated, the music was cut to start from approximately the 20 second mark. By the time the main theme comes around, the ride has already started and is in mid-swing at the back of the chamber. So, why not use the full score?
When the music starts, the loading lights dim, and the gondola stays still for about 2 measures or 12 beats, then it unlocks and starts to sway. After 2 measures of this (or 5 seconds), when the violins come in (for four measures or 24 beasts), the gondola raises up towards Durga, with the vehicle still unlocked/swaying.
When the guitar chords come in (the "bwahhhhhh bwahhhhhh bwahhhhhhbwahhhh") at about 23 seconds into the song, Durga's eyes light up blue, red, and yellow, fluxuating between the three. At the same time, the gondola does a controlled flip either forwards or back, then locks into place again. The gondola stays in that position infront of the goddess until the main theme comes in (about 34 seconds into the song), when it releases and goes into the 2 flip cycle (thus making it a 3!).
Lighting and Music- A more realistic change would be to change the lighting and the music. I think this could work, and it would replace the loading and show music with the same piece, Chasing the Storm by Patrick Doyle (opening theme in "Thor"). Have the beginning to 2:20 loop throughout the loading/unloading process, and have 2:21-2:44 loop until the tail end of the ride cycle, then go from 2:45-end of the piece for the finale of the ride.
Lighting-- When The Crypt operated, the lighting kinda seemed random, more often than not. There were a few places where the lights matched up with the music, but other than that, it was just awkward. To fix this, I have simple yet effective changes:
- When the music crescendos, make the lights do that too. Maybe start bright then immediately fall back down to soft, then get brighter?
- When a suspended cymbal or gong plays, make a strobe light or just a flash of colored light light the whole goddess. Simple, yet very effective and cool.
- At the end, have all the lights used in the show light up, where the music goes "bum" at the end of the piece, then quickly die down (to be replaced with the brightening loading/unloading lights).
- Maybe? Add fog (since it is succesful at Universal)
So, post away!
EDIT: Here's the score from Thor:
