they are samples of the stops. from memory you have 6 months to use up your ticket. it would be a good chance to see the world but you would be stuck in youth hostels unless you made of $$$$. also i would be going with someone(or more) people that you really get a long with, for the obvious reasons of making big decisoins etc.
hope that helps.
