My friend and I are seniors in high school and want to go backpacking across Western Europe (continental) during the summer before college. We want to start saving up for it now, and are wondering about how much we should expect to need assuming we use couch surfing as much as possible, eat relatively cheaply, and backpack/hitch a good amount. How much do we need for both of us, including flights?
Another question: I can claim EU citizenship using my mom's Polish documents, but it's a lot of annoying paperwork, I would have to visit the consulate, etc. Would having an EU passport make our trip any easier? My friend would just have her US passport (she's US citizen, I'm dual US-Canadian).
Finally, how do we go about planning a trip like this?
