Thanks for the advice both - my only problem is that flights don't fit as neatly from some of the Eurozone countries. I'll keep looking into it!

On another note - if I can get all the schedule sorted then I'll hopefully book in the near future. Has anyone had experience of booking the ticket online? My biggest concern is whether I can change the first flight or not - I've read that you can but also that you can't so a bit confused...
