Thanks for the feedback, guys.
I did the Richard Petty Driving Experience at Walt Disney World Speedway back in 2007...1.1mi 3-turn track. For $399 you got a great pre- and post-race production, training from seasoned racers, and a nice photo/plaque package I still look at today and remember well. 8 laps, 115-121mph speeds...I'm not a fan of NASCAR but it was a great experience.
I don't know if bumping around Tuttle Mall at less than 60mph for a couple laps is going to do it for me, even at $99+. I'm sure they'll have a great take-rate though...
