Re: Why didn't Kirk just contact Sulu?
Well that would make more sense, type into the computer what you want to say and have it translate it into Klingon for you to speak.
I always thought that a perfect translation would be more likely to tip off the person on the receiving end that something was up.
As for the original question, maybe Excelsior
ferried delegates to the conference. Which would be how Sulu knew where the conference was...
