low budget

HELLO! A few of my friends and I planning to go on our very own Eurotrip! We’re juniors in college looking to let off some steam before our final year. I have $4000 to spend (not including airfare and a eurail pass, I’m paying for those separately and in advance) for 8 weeks of travel. Does this seem feasible to all the experienced travelers out there? We’re planning on taking trains at night (that gives us 10 free nights of lodging) and hopefully we’ll spend 4-5 nights crashing with friends we have over there.
