It's enticing to get a stadium ticket for Arthur Ashe, Louis Armstrong, or the Grandstand. But if you are there during the day and spend all day inside the stadium, you could be missing out on some amazing tennis going on on the smaller courts, which offer courtside seating to anyone who walks up.
You can also walk over to the practice courts to see some of the greats warming up before their stadium matches.
While I was at the US Open this year, I saw the top-ranked professional Stan Wawrinka play right in front of me, and I watched as Serena Williams warmed up on the practice courts right before her evening match.
Regardless of your reasoning for heading to the US Open or what time of day you're attending, there is a lot to do and see while you're there. Hopefully, avoiding these common mistakes will help you have the best time possible.
