Dave Pierson from the Ohio Valley Audi Club has been doing this Daytona HPDE for several years. He is a really cool and experienced track guy - with lots of stories and a comfortable way of speaking. If anyone has any questions about the HPDE portion I suggest you drop Dave a line - his contact info is on the PDF attached in Kman's Post #1. The track is the real deal, with incredible banking and speeds.
No, it is not necessary to join their club - those fees are the same for us too! Also, we have the same room rate at the Hilton Garden Inn near the track - $99/night for best avail room. Of course, you can stay where you like if you prefer to be on the beach or more luxurious accommodations. Many choices in Daytona.
