I am going to be in NYC next week for a day on business. Will have some extra time and have never been to the city before. As a tennis fan, I am immediately drawn to the NTC. I saw online there are "behind the scenes" tours for $25. Has anyone been on this and would it be worth it? Are there any tennis shops worth hitting up in the city as well when I'm there? Thought about getting a court for an hour to be able to say I've played where all the greats have played, but seems like it is tough to reserve one.
