I personally prefer the CC license over GFDL if you want to be able to more easily collaborate with other sites. GFDL is a pain, unless your main goal is to be able to directly copy info in from Wikipedia. As for Wikitravel, they started off as 1.0 and have never upgraded... we've had conversations about it, and basically believe that 1.0 and later versions are compatible, but I don't know a whoooole lot about it.
