As others have pointed out, if you're flexible you shouldnt have a problem. We only stay in studios for 2 or 3 nights at a time, and we book most of our trips 3-4 months out. In the last year alone we've stayed at BLT and BWV twice each and have had no problems getting them. But there have definitely been many times I've called and the only thing avail was SSR or OKW.
