Question first, was there a reason why they couldn't put real flame effects inside in the first place? I think I read some where there was some kind of violation code or something.
Also, why can't you see your ride photo anymore??
Theme the outdoor queue more like the desert with ancient Egyptian columns and statues. Similar look to the studio tram tour's Mummy tomb (which should get a facelift). The tent shades should be like an explorer's tent. The side of the pink queue building could be more of a themed Egyptian stone structure ruins. Exit bridge themed to wooden scaffolding. metal queue bars inside themed to wood. GET RID OF THOSE USELESS EXTENDED QUEUES TO THE SIDE OF THE SHOW BUILDING ON THE EAST SIDE. JUST USE THE QUEUE ON THE SOUTH SIDE. Add indoor queue themeing to the southeast. That includes what's under the roof infront of the "tomb" entrance. Move the "tomb" entrance so the Express & single rider line is still on the left and tomb entrance on the right (essentially left of the current car display. I hope that made some sense) Move the car display near the mummy shop. A booby trap or two could be added. One could be "Don't touch the rope", once touched, a crate above you almost falls right on top of you. Touch one of the sacred jars (the ones that have body parts in them) and the room you're in shakes like a minor earthquake. Could now also have Orlando's wooden wall & crates theme. Not sure if it was explained in the pre-show video yet, but they should say "Once Imhotep has risen from the dead within the power of the eclipse, he must sacrifice enough human victims to keep those powers...", just so it's really explained to us why he wants our souls
There could be a "wooden" doorway before you enter the ride past the load station.
Replace the 1st head nodding mummy with the Imhotep jumping AA. They could just move this mummy more in the mummy tomb section of the ride. Instead of his hand waving at a victim, he waves at you and says: "Roarr! With your souls, I shall rule for all eternity!". Instead of popping through a sarcophagus, he pops through wooden doors. Mainly because he already broke through his sarcophagus in the themed queue.
Not sure what to do with the explorer being eaten by beetles for an AA. For now, a movie projection.
The treasure room could be lit by those mirror discs. When the room is lit from the warm color to the green deathly color with the sound of cracking lighting, 1 eye-lit mummy guard from each side could pop-up vertically quickly and not just flipping them up from a horizontal position. Could add orange lit smoke effects shoot up when the mummy guards pop-up and yell. Then slowly back down in the mist to start to get ready for the next riders.
Have those two stiff (pun intended) mummy guard figures be AAs staring from Imhotep and as you enter, stare right at you as you move along. Swing their arms a bit like they're ready to smack you with their swords. Widen their mouths and groar. Blinking glowing eyes. Going along with the movie projection behind Imhotep, have collapsing /shaking columns at your side. In Orlando's version, after the jumping AA, there's a part where the walls light up to the treasure room. Add that in here with the Imhotep AA room on both sides behind the shaking columns. Everytime he says the Egyptian curse words (pun intended), they light up and glow towards him (which is about twice).
Now here's a cool idea, still in the same room with Imhotep AA: Under him in the dark black tunnel, it's a sand fall (like a water fall, but with sand). And has Imhotep's face on it while he's cursing you (it may be repetitive from the treasure room, though). When you blast off, you burst through the sand fall with Imhotep's mouth wide open. The effect is accomplished with the use of fogscreens, like in Disney's recent Pirates of the Caribbean update for the Davy Jones effect. Or after every few rides that pass through, it can change to a waterfall. Makes it seem random for repeat riders. The sandfall can refer to the 1st movie and the water fall refer to the 2nd movie. In Orlando's there are colorful strobe effects before you launch, maybe add that during Hollywood's launch, if it's not already there... even though you're blinded by the photography light, it wouldn't be too much trouble.
In the beginning of the coaster track, Imhotep says: "Welcome, TO THE UNDERWORLD!" Just so people can actually GET the idea of where they went and why this dark coaster section. Maybe have the blacklit artwork be movie projected? Instead of being still, they can actually move around. But this might produce more light inside the coaster section. If that's the cause, the blacklit artwork is fine.
Before the beetles, you pass through an effect found in Orlando's version. You see an animated Imhotep(?) head that widens its mouth and you pass through a green-lit section. You enter the beetle room. Move the current blacklit character elsewhere in the coaster.
Now for the turntable ending, I have 2 ideas.
1) When you back into the turntable, SFX sounds and lights are made and Imhotep says: "My powers, what is happening?!". The projected eclipse is fading away and Imhotep says: "The eclipse! NO!!".
The black hallway before you go to the load station could be themed with treasure and mining equipment, either physical props and/or wall paper. And a doorway that separates the load station and this 2nd treasure room.
2) When you back into the turntable, Imhotep exclaims: "My powers, the eclipse is over, NOO!!" And a projected Imhotep face breaks apart and fades away as you back up into place (could probably use Orlando's projection when they spin you around. Add special colored light of faces moving up and away around the black hallway. Like how Shrek 4D has those special lighting effects to the side of the screen). With the ever so charming music finale que. Relocate the blacklit character that's here elsewhere in the coaster. It looks like a load station, with the Egytian ruins theme still going on. To your left (under where the projected Imhotep face would be) is where you see the "control room". The "ride operator" says "Welcome back. Please remain seated until...AAAHHHH" operator's life sucked out of her... CRASH! BOOM! Maybe water effects to simulate glass breaking? Imhotep takes over the controls and says "Death is only the beginning! Ha ha ha ha!" while you spin (keeping the current music) around and flames emerge above you. Pump hot air in the room. Then smoke/flames POOF at you.
The black hallway could use some stone wall themeing and maybe mining equipment props.
EDIT: Perhaps in this converted hallway, have a mirror hanging above our heads (same theme as the pre-show video). It looks like one of those "See your photos and purchase at the store" type of things. But either in video or still photo, it morphs/transitions to a group of skeletons riding the attraction, either from the ride-photo camera or real time as your going through the hallway. OR when you briefly see your ride photo, it transitions to the group of skeletons riding the attraction. Imhotep: "Now you shall walk among the living... as the undead! (satisfied grunt).
Continue the Egyptian theme through the exit hallway. If the House of Horrors got rid of their popping up mummy from behind the cage, use it here before going outside. Perhaps have video screens for your ride photo here as well. Flat screen TVs, baby!! Along 1 side of the Mummy wall mural. Should probably have 1 new mural that reflects Mummy 1 & 2. And soon 3.
PS- I prefer the coaster ride music of Hollywood's version compared to what is used in Orlando's version.
