There are a variety of driving events at VOI 's in general...but, I cannot speak to those scheduled this year as I am not attending.
In the past, there has been an all day cruise...one can drive one's own Viper or travel in a bus that is provided.
As far as track driving, it is generally in the 60 mph range, with an instructor in many/most of the cars...speeds kept down by large numbers and the fact that some drivers have NEVER been on the track before this event.
PERSONALLY, I will NOT DRIVE on a tire that has been repaired while in a "performance car"....especially Vipers, Porsches, Ferraris, etc....period !!
