N2 Trackdays also discounts track day packages, and you wont be stuck going to one track either. You will have the option to attend any of the track days N2 runs, from PIRC to Road Atlanta, NCBike, VIR, etc (lots of choices).
There are 6 day/12 day/18 day/ and season track day packages available. When the days are averaged out, you pay less per day than you would buying them individually on 95% of the tracks we run.
The 12 and up track day packages also include the Elite Membership (Normally $250) and allows lots of flexibility, my favorite benefit of the Elite Membership is the ability to cancel up to 8AM the day of the track day and you get your day back.

Let me know if you had any other questions. The packages aren't available for sale yet, but will be very, very soon.
