Went on the 15th with the same idea as you. Arrived to USF at 9am and they were already open. Walked straight to the Mummy, and went into the regular queue. Funny thing happened. You actually walk into the right side of the building, and then walk back outside to the front. People were freaking out thinking it was the exit of the ride. I was laughing at them, and said to keep going. Yes, you walk back outside, and then into the main building. The queue is nice, but nothing fancy. You will see most of it using FOTL. On our journey, there was no wait, so we didn't even hear the story on the tv screens overhead. We just kept walking up to the loading station. Along the way, there are some characters that will scare you. FOTL simply takes you around the main queue. You can still see it, but you by pass it and go up the stairs to the loading station.
Go ahead, get there early and go thru the main queue just to try it. Then go back thru the express line and breeze up to the loading station. In the afternoon at 4pm, this line will be 15 minutes, much better than the real line at 90.
Oh, and see if you can sit in the front seat, left side, it's the best.
If you don't get it, don't worry, you probably will on your next ride.
And hang on at the top of the lift, there is a sharp turn to the right.
