NYC Trip: Broadway Shows

My trip is next week and I am increasingly becoming nervous/excited as my departure date draws nears. Other then the US Open, I am going to see a couple of shows on Broadway. I currently have tickets so see Xanadu and In The Heights, but I might see one more show but I am not sure. The group I am going with are going to see August: Osage County, but I won't be going with them because I plan on meeting with some some friends. I wouldn't mind seeing Wicked, Spring Awakening or South Pacific ... but I will see what my schedule allows.
