When it comes to the three Mummy's, Orlando/Singapore has the much better overall layout. While Hollywood's Mummy has the better backwards section, it'll always be wonky due to having the turntable at the very end of the ride which kills the flow of things.
It also hit me that amusingly none of the versions can get a ending right, case in point.
Orlando - A very abrubt end with Majai symbol and sudden Brendan Fraiser coffee clip.
Hollywood - Turntable eclipse which gives it some sort of fitting ending, but thanks to the turntable it always comes off anticlimatic. (The original ending wasn't much better as that felt like it was building up to something, making things even more anticlimatic.)
Singapore - While Singapore came up with a good overall story of you racing to find the Book of the Living before Imhotep does, they ended up pulling off probably the most confusing ending of the bunch. During the ride near the "end", Imhotep ends up getting the Book of the Living and unleashing a friggen curse on you. So this should be a "the bad guy wins" kind of ending, right? Well when you do reach the end of the ride, you pass through a wall and Imhotep is trapped in a sarcophagus for some unknown reason and saying Death is only the beginning. This ending makes no sense whatsoever considering he got the book and unleashed a curse in the previous scene.
