New York City Sweet Sixteen?

Hi, my 16th birthday is coming up in a few months and I need help deciding what I am going to do! I live outside of Manhattan so I was thinking about taking around 20 friends on a party bus in the city. I have no idea what we can do in the city though :(! I don't want to just have a dinner. I want to do something fun too! I was thinking maybe karaoke but I do not know what to do yet. Does anybody have anything fun to do in the city?!
