What are the speakers mainly discussing?

M: Wow, the line at the taxi stand looks really long. l wonder how much time it will take us to get a ride to the convention center.
W: Well, the convention doesn’t start for another hour. Maybe we could take the bus instead.
M: That could work. l just want to be sure that we’re there for the lecture on international finance.
W: I’m looking forward to that lecture as well. I know there will be introductory speeches and messages from the sponsors before it begins. So, the bus should get us there in time.
