I was at a private presentation there a month ago for Lotus owners. They specifically pointed out one of the many benefits of giving them a giant pile of money was that they would not be renting out the track to those pesky "Club People". I s**t you not. The vibe was "We want rich people to buy in so we can get richer". They made it quite clear they saw club rentals as very non desirable.
The joke was on them if they thought Lotus owners are rich! But they did mention Ferrari's as a desirable car to have at the site about a million times. I quickly noted I will probably never drive there.
but the proposed track layout looked really awesome. Long, and many possible variations. And yes there is no overnight stays allowed at your track pad. You can store your car overnite however.
