AirBnB had 200k listings and claimed 3MM guests at the end of 2012. I do suspect the average AirBnB stay is shorter.

Do note, from the Hyatt 2012 10-K "As of December 31, 2012, our worldwide portfolio consisted of 500 properties (135,144 rooms and units)."

With availability of 300-365 nights a year, unlike AirBnB, this amounts to more than 40-49MM room-nights they can sell. Occupancy rates varies of course, but even at 70% average, that's a whole bunch more people than AirBnB.
