Interesting, I asked Venice why Bretton woods was chosen as the location for the conference. I got the same answers as Gemini, but I also got this little nugget:

Personal connection: Harry Dexter White, a key organizer of the conference and a senior official in the U.S. Treasury Department, had a personal connection to Bretton Woods. He had vacationed in the area before and knew that the Mount Washington Hotel would be an ideal venue for the conference.
