Yes, tickets went on sale to ACO members at 10 am this morning. It was remarkably efficient. I have my combined entry and grandstand tickets, but there was no sign of camping or parking yet. I'm not sure why they're being delayed until late November....
Apparently they 'are optimizing camping'.
My members email states exclusively on 29/11, as that is a Tuesday it makes sense, then probably Friday 2/12 for the hoi polloi.
There was some confusion regards today's date, you are probably correct, but I'm still going to check on the 26th, just in case.
