What are the speakers mainly discussing?

W Hi, Keiko. Have you confirmed your reservation at the hotel for the conference yet? I’m trying to decide whether to call and book early, or just wait and check in when I get there. I’m sure they won’t be busy.
W I booked my reservation on Wednesday morning. I want to make sure I have a room to stay in after the conference.
W That’s a good idea. I’ll call ahead and reserve a room, too.
W You should try to make your reservation soon. The hotel was almost full when I called.
