I'm surprised no one has mentioned Esperanto (http://en.wikipedia.org/wiki/Esperanto http://en.wikipedia.org/wiki/Esperanto). It's a meticulously systematic language with a wonderful spelling system and intuitive grammatical structure. I speak a few languages, and was able to pick up Esperanto at a conversational level in around two weeks rather than the customary 6 months to a year. Plus there's the bonus of the Esperanto travel network, where people all over the world allow others who speak Esperanto to stay with them for free/cheap. Definitely recommend it anyway - and good idea.
