hi im sorry for posting this twice but i cant delete it from the other forum and im getting a bit paniced and need help...sorry
!
ok im leaving in like 5 days and still havent got a rail pass(and dont know if i should)
im going to france,belgium,the netherlands and germany 4 like a month!!
i was just looking up french train times(which i cant understand!! ) and they seem really pricey €230 from nice-paris....i really had not anticipated these kinda prices for gettin from a to b!
so i was going to get an interrail pass.... but it says on the terms and conditions that it only offers a reduction on some journeys and that also some journeys must be reserved!
how the hell to i find out how much i do have to pay before i go over(any website suggestions?) and how do i reserve when they want to post me the train tickets...as i wont be here to collect them!!

please anyone who has opted for this option....share as much as possible because i am utterly clueless!!
