My take on Culture Vulture is a term to describe someone interested in all aspects of culture and who enjoys experiencing this while traveling.

There is an interesting description on the urban dictionary.

http://www.urbandictionary.com/define.php?term=culture%20vulture

A person who loves art, music, movies, and dance, and all forms of culture so much that they consume whatever they find, whether or not it's any good. Like birds that scavenge by the roadside, culture-vultures feast on art wherever they find it.
