What are the speakers mainly discussing?

W: Hi, Brad. So, did the front desk staff have any information about the best way to get to the conference center?
M: Yes, there’s a free shuttle bus that leaves here from the hotel parking lot. They said the trip might take up to an hour if the traffic is heavy in the road construction areas.
W: Well, it’s about 9 a.m. now, and I sure don’t want to arrive after Sandy’s keynote speech begins at 10. They usually don’t let people into the auditorium after the speeches begin. Is there another way to get there?
M: We could share a cab. It’ll get us there a lot quicker, and it won’t be too expensive if we split the fare.
