The Dream Trip

Sydney gets an idea: when Tara turns 21, they should plan out a road trip around the Europe. Since she's going to be fresh out of school and the others can move their semester, everyone agrees. The girls get even more excited when their parents let them go.
Mind you this idea got developed on Sydney's birthday party in November. Since then, the girls have been spending each weekend together planning the road they'll drive, booking hotels, finding "secret" places that tourists don't visit, and most importantly modifying an old van of Kacey's grandfather...
When the road trip starts everything is perfect. Too perfect. They travel through Hungary, Croatia, and Slovenia collecting life long memories. The trip catches rough turn, when in Italy, the van breaks down and the repairs are going to take two weeks.
This means two things: they either cut their trip short and return after the repairs are done, or prolong their trip by two weeks. While they spend the two weeks in a little Italian city called Belluno the girls experience things they never dreamed of. As the two weeks come to an end, they have to decide what to do.
Do they stay longer in Italy because they are having the time of their lives? Do they cut their trip short? Do they continue the road trip?
