It's not that complicated really. I buy front row seats on the TV table. so my entrance in the "event area" is included.
But they sell day passes, or a 2 day, 3 day, etc
This gets you in the door, and into general seating which is bleacher style.
95% of the seating is general seating, with the front seats in every row being reserved for VIP status. I don't know the fees, but they are VERY resonable.
I am guessing $ 10 bucks for the day. They have afternoon passes and evening passes, or entire day passes.
The matches are basically every 2 hours--IE: 1PM, 3PM, 5PM, 7PM, 9PM with approx 14 to 16 tables going per session.
Hope you get a chance to go.
I enjoy the US Open, and 2nd favorite behind the Derby City Classic.
Very professionally run event, BOTH OF THEM !!
Good Luck
