What the Mummy has going for it is is continually ranked as a ride with the highest guest satisfaction. It's 12 years old and it still brings 'em in. I know it's my favorite at USF, it's many of my friend's favorites, and I hear more positive things coming off that ride than I do any other in that park.
I wouldn't be terribly upset if the ride got re-themed(Back to the Future anyone?), as long as that ride system stays in place. It's just so much fun with just enough thrill to make most people happy.
I love Mummy but that's about as thrilling as I'll get, lol. I need to step it up.
