I will be in NYC next week and my sister and I are planning to go to the USO for 1 day we just don't know yet which one.
Is it possible to just line up in the morning and get tickets for the day? If so can you just get a ground pass or even tickets for arthur ashe?
For example if I would wanna go to tonight's night session. Should I just go there to the ticket counter or should I order them online? I guess if they have seats remaining they might sell them for less on site, wouldn't they?
