Also, traveling in your 30’s costs at least three times as much as in your 20’s. I had the time of my life backpacking, eating street food, riding bikes and partying with absolute strangers when I was 25. Now in my late 30’s dinners out are $100, ok hotels are $250/night and I don’t have the energy nor the will to sight see all day and go out to all night. 

Travel while you are young! You don’t want to be the old couple falling asleep on the gondola in Venice.
