I am pretty sure that the general admission tickets at $ 20.00 per day. Those gives you pretty good bleacher seats for the first several days of the tournament, but those seats are not very good when it gets to the quarter finals, semi-finals and finals. You really need to have the VIP seats to be able to see those matches up close.
Separately, I have a few front row VIP tickets for sale for face value $ 150 apiece. These are good for Thursday - Saturday, October 17 - 19, 2013.
Three of us are still going, but 3 had to back out. See my ad under the For Sale section.
