Checklist traveler

One who frequents a place/country/city just to say that they've been there. Checklist travelers tend to only visit for very short periods of time but will brag that they have 'done' that place.

Barry : Everything in Thailand is amazing! I love the exotic culture and the landscape. All the people are so warm!
Sally: Sounds amazing! Where did you go?
Barry: Bangkok, it was a 24 hour stop-over on my way to Australia.
Sally: Barry, you're such a checklist traveler.
