No idea on baseball, but this is slightly related. We have a minor league hockey team. A couple of years ago, our hotel got to house the visiting team for the second round of the the playoffs; games 3, 4, and 5 of a best of 7.
The reason we got to house them was that the normal hotel, the one that sponsors the team, gave away all the rooms that they should have reserved. Presumably because they didn't expect the team to make it out of the first round. The following year, there was a new hotel housing the visiting teams, with a radio add that also a slight slam at the old one that played off of the name.
I imagine that it's in the best interest of the hotels, security, and venue to plan on the game going 7 and then taking a loss on those nights if the series ends before 7.
