Boy, lots of misinformation here. Whether TT preserves are where you want to go or not, I can tell you from spending the better part of the last 6 months at Thousand Trail preserves on the west cost, I have always been able to reserve in, even on very short notice, have had great campsites and while there are annual leases, they do not occupy all the good sites.
And we have never felt inferior to the "regulars".
