Italy unnacompanied? Me and my friend want to travel to Austria to go skiing in December 2012. We want to fly into Milan and take a train to Austria because the flights are cheaper to Milan from our area. My question is, we are both 16 at the time, and we don't have an adult with us, but we have parental consent letters, will we be allowed to enter Italy? We both have US passports. Because of the Schengen agreement, we will be able to cross the border into Austria on a train with no problem, right?
