We were in building 9 from Nov. 9 to 23. In MHO this is the least desireable location. Although building 10 backs onto International Drive, as an earlier response said, there was little noise. However, if you are spending time on the patio of building 9 you do get traffic noise. That being said, the noise was only evident when on the patio, not when inside with windows, doors closed.
The resort was great, enjoy your stay.
