I heard about that [HTML_REMOVED] forgot, is that all summer or just for events like bike races ?
All summer from what I've seen the last two years. Try and get a spot on the right side of the lot, its shaded in the morning and you'll get some extra sleep.
I've also slept in the back of a truck in the gravel lot at the bottom of the lift, we were a far enough away that the golfers wouldn't see us roll out of the truck in the morning. As long as you're not doing anything crazy I don't thing its a big deal.
Silverstar you can stay in the parking lot. When my friends stayed there 2 years ago they had a power outlet and a communal fire pit available.
