Do Dream Racing and get the Ferrari GT430.  

The difference between Dream Racing and Exotics is that Dream Racing is inside LVMS, and Exotics is outside. Also, with Exotics, you don't have the option of driving a GT430, which is not the same as a streetcar Ferrari 430.  

5 laps is not enough to fully take in the GT430. If it's your first time driving that fast (0-60 in 3.5 seconds), you won't get comfortable until maybe lap 4 or 5 and then it's over. The racing simulator is amazing and identical to the car and track as well, minus the G's you'll feel on your body.

I just did this back in August and I highly recommend them.

There's also WCD.

I did the World Class Driving gig 2 years ago.  At that time it was down at the Lake Mead State Park...5 different exotics.  Not necessarily high speed, but still a kick-ass good time.  Now they do it out at Red Rocks.  I've been told the "isolated" nature of the RR allows some opportunity to step on it a bit.    

I've looked into Exotics and being able to run these "babes" on a road course is certainly intriguing   I wasn't aware of Dream Racing.  They seem relatively similar. It is my understanding Exotics uses the "outside" road course at LVMS.  I'm a bit surprised the market can sustain both enterprises.  And now WCD has plans to build a road course facility on the south end of the strip.    

I'm planning to do one of them next month with a "fast and furious" partner.  I just haven't decided which option to go with.  The road course experience has an instructor riding with ya, while the WCD deal does not.   Decisions, decisions!
