Rat sightings in hotels up 30%.

From USA Today:

Have you seen a truly unwanted guest - I'm talking about a rat - scurrying about your hotel lately?

Chances are you have, if TripAdvisor.com's unscientific "rat" analysis conducted for USA TODAY's Hotel Check-In at all resembles reality. By analyzing its January and February U.S. hotel reviews, TripAdvisor found that reviewers mentioned the word "rat" 31% more times vs. a year ago.

The analysis, of course, is not scientific. The uptick could easily be explained by an increase in the number of reviewers writing about escaping "the rat race" or partying at hotels favored by "the Rat Pack."

But it could also hint at a slight uptick in rat sightings this year vs. last year.
