Doing an interrail trip with friends after finishing school is really popular, and be me and my friends were planning on doing it but I was wondering how/when to do the trip because of having to enroll to uni and all that ?

Can you take any size bag or is there a limit?

We're also trying to do it as cheap as possible, how much would you recommend i save for 2-3 weeks?
