I taught a class overseas in January. I now have a sabbatical - doing some studying and other projects for a semester. That said, I stayed overseas. Having reduced my debt prior to this, and having the skills to be a pretty frugal traveler, I am managing not to go into debt on this adventure.
I don't do all the fancy tours, and my pleasures are pretty simple; Apfel strudel in a cafe for breakfast today, bread roll and a clementine from the store for my lunch on the train.
