Jump on this quick (and affordable) seven-day tour of some of Europe’s greatest cities. See what’s so nice about Nice, snap the expected “holding up the Leaning Tower of Pisa” shot, and then explore Gaudí’s famous architecture. And hey, think of the food to be tried on a tour from Rome to Barcelona! (Good thing you’ll be walking so much.) Travel on trains and leave the coach bus behind on this life-changing experience.
