Does having a business-focused rep help a destination?

From this post on the Cvent blog, it sounds like the answer might be "yes," at least in D.C.: See Is the DC Hotel Market Faring Better Thanks to a "Business Only" Reputation?

I know that the glitz and glam destinations are hurting, as are some of the more entertaining places (though D.C. can be pretty entertaining, in my book). I'd be curious to know if other more-serious types of destinations are seeing the same thing, or if D.C. is just blessed with a strong association-meetings market base and lots of tourists staying closer to home this year?
