I don't believe they will tell me if I called the hotel, would they?

Ok, let's just say there's this farewell party for my club, not just from my school, the same club from other school, I know where to go, the number of the place BUT the time and date. First they say Friday(tomorrow) and some time than they changed it to something else, now I'm confused. Can't ask my friends since they're not going, can't call the president now. I don't believe the hotel will tell me if there's a reservation if I ask right? It's private, after all.
