Even though everyone has the tentation of visiting the famous european cities during the summer, the truth is that the best time to do it (thinking about the financial budget that you may have) is this Fall.
A recent study taken by CNN showed that the saving could go anywhere between 30% and 60%, allowing you to witness the strenght of the Fall market as the best alternative for those who simply can't afford the glamorous trips during the summer...
Anyway, your budget surely tells the story and claims when you must travel for itself, right? Just pick up the right destination and the season when you take the trip won't really matter, you will see!
