The Simpsons was confermed in an article that i found of a thead at XtremeCoasters.com
Top Three Parks:
1) Islands of Adventure
2) Bucsh Gardens Europe
3) Six Flags Magic Mountain
^^I would pass on both Mummy and BTTF to get more laps on MIB. I did not overly care for Mummy when I rode it in June.
I didn't think Mummy was all that bad when I rode it last year, but I guess I expected something more -- like, for instance, a longer "coaster" section. The themed "vehicle" parts are sufficient, but the building is ridiculously underwhelming by comparison. Certainly not worth the hour-plus wait (in a park where NO OTHER RIDE had a wait).

Mummy is the best coaster in Orlando. It's about the same time as any other coaster too, if you don't count the show part.
Single rider line, man. Greatest thing since sliced bread.
Hour wait? Um, more like walk-on in the normal wait line. Did it three times and then my body told me that the roughness of the ride in the dark was no fun anymore. It's a take it or leave it ride IMHO.
I will confirm what Gator and Rollocoast said.
Having just come back from Orlando a couple weeks ago, BTTF was packed but being a single rider gave me multiple rides on Mummy and MIB instead.
