Sept. 29–The dismal performance of the Baltimore Ravens last year produced some fumbles off the field also — at least that's one possible interpretation of a new analysis showing game days had minimal impact on hotel room revenue in Baltimore.

Home football games boosted hotel room revenue in Baltimore by just 2 percent last year, according to the analysis by STR, a hotel data and research firm. Only six other teams in the 32-team NFL did less to boost hotelier margins. (Some did far more: room revenue in Green Bay, Wis., for example, jumped more than 300 percent thanks to Packers home games last year.)

Even in 2013, when the Baltimore Ravens won the Super Bowl, home games appeared to boost hotel revenue by only 12 percent — about the middle of the pack.

The analysis looked at room revenue on game days compared to what might have been expected based on other, similar dates, said Steve Hennis, STR's vice president of consulting and analytics

But Hennis said the impact is shaped by multiple factors, not just wins. Among them: the size of the existing hotel market, the intensity of the fans whose team was competing against the Ravens, and how remote the stadium is.

Hotels may alter rates or block rooms in anticipation of NFL business, while other types of business — for weddings or conventions, for example — may decide to hold off because of the games, which may be why home games in some places appeared to have a negative impact

"There's certainly a lot of different moving pieces," Hennis said.
