DH just did this July 5th so I think I can help....You call 1-800-BE-PETTY to mke your reservation.
You should reserve in advance as they only take about 10 drivers at a time and only on certain days of the week.
You pay with your credit card when you make that call
If you have
AAA you get a 20% discount...be sure to mention the AAA when you call, if you have it.
They send you liability waivers and a letter with all the information you need to know before the drive.
The 8 lap driving experience takes about 3 hours.
Choices of times were 8am or 1pm.
You have to be there 30 minuted before your reservation.
When you arrive they try to sell you a 3-lap ride along (140mph) to go with your 120mph max driving experience.
The add-on costs $79- cash or credit card.
They take dh's photo beside the car and in the car so they can sell them to him later.
Dh bought the plaque (which is really neat looking) for $70ish.
Family can go watch the driving but there are no stands to sit in, only a tent in the midfield. No A/C either so being summer and having small children we chose to send dh to drive while I played in the pool with the kiddies.
He, of course, loved it (but wished they would have let him go faster.)
If you have any other questions I'd be happy to try to answer them or get dh to the dis to answer them himself....have a fun trip!
