Yeah you have to get over the "politeness" hurdle if you want to seriously learn a language.

When I go to Spain, I will always try to speak Spanish and if they reply in English (which they often do because I make mistakes and/or have an accent), I just keep replying in Spanish. That may be seen as "rude" or inefficient by some (although others probably appreciate the effort), but it's really the only way you can keep making progress. (Of course, if it really gets too complicated you can still switch - but usually people switch way before they've reached the end of their skills.)
