So, I took out the external link to Wikitravel. I didn't think it was particularly useful on this stub, and I personally didn't like the appearance of low-class hit-mongering.  If this becomes a real serious article about travel, well, probably a discussion of or link to Wikitravel would have a place in it. For now, until this article takes on a real shape, a single extlink just seems kinda opportunistic.
