hi mr bills,
ok i did this route with a friend in june for three weeks we had to come home early due to death in family.
we flew to brussels one nite there then one nite in bruges. this place is gorgeous do the cycle tour its called quasimodos i think and u get a free drink try the cherry beer yum!! in amsterdam go to anne franks house, red lite distric total eye opener and there is a free 3hr tour operating, ask in hostels.also in berlin there is a free 3 hour tour, he wrks on small tips and it does east and west berlin. in poland we went to krakow, its lovely and auschwitz is an experience in itself, definitely go. we also went to prague, not too gone on it but everyone is different, very architectural and nice. in italy we spent three nites in rome, go to vatcian city, we spent two hours queueing but u see the sistine chapel, etc, go to st peters basilica and square, pantheon, collesseum etc, rome is incredibly hot and expensive, outside the collesseum a contour bottle of coke costs 5euro. i think people shoud visit naples and venice although i haven;t been (YET!!). u will prob need to get an overnight train from rome to paris if thats ur plan with the interrail ticket it costs 25euro and u shre a cabin with 5 others, the seats are pulled down so try get top bed for more air and room, paris is amazing, go c eiffel tower, sacre coeur, lourve, arc de triomphe etc. OK really hope this helps, sorry dont have info on the other places haven;t been there yet!
message me if more info needed, katc
