Yeah I don't put a percentage to it either. We usually alternate between international trip and domestic trip every other year. So this year was New York. Last year was South America. Before that was L.A., then Korea, then San Fran, Hong Kong, etc.
However, when we do travel, we tend to travel cheap by booking apartments instead of hotel, public transportation instead of car rentals and cabs, limit the number of fancy meals. Also, I skimp hard on souvenirs lol.
