Well, firstly we must discuss that MAJORITY of people didn't travel purely of leisure in this time. And if it was, most did so in their own nation or in those very nearby. Dispite this, you had some travel by cultural ethuist and others that were on business. This made up much of what may be close to our present day "vacation", many seeing the light of god in the insert nations cultural.
All in all due to the high nationalism of the time, most tourism was cultural with very little goning out of their way to see "Argonnerwald" or the wonderful "Kurische Nehrung".
