everyday up to the semi there are 250 tickets released for Centre, Court 1 and Court 2 each - after that a ground pass will get you round all the courts and into the standing area of court 2. Some days are crazy for tickets especially the first saturday and 4th round where last year when I was there you needed to camp and queue at crazy hours. We got down there before 5 for the fourth round and the best we could get was court 2. Its piss easy to get tickets for the womens quarters, queued very early last year but I'd say even being in the queue before 8 and you would get centre. As far as I know I'm correct about the amount of tickets released but to be sure check out the official site. Have a ball at Wimby, last year was my first time and it is a really great place!
