1 july to 4 october:
(i have been to barcelona, nice, amsterdam, rome, venice, paris, pompeii and dont want to revisit)

spain and portugal whole month of july, 1st week august cannes, monaco, cinque terre. at this point my main goal is to get to sicily and spend a week in palermo. after this get to brindisi and take ferry to corfu and spend 3 weeks island hopping (corfu, athens, santorini, ios, mykonos, maybe crete)

so now im on 2nd week september from greece get to croatia and spend a the week in sarajevo and dubronic (ive heard of this amazing forest in croatia with waterfalls and rivers, not sure where or how far is it).
3rd week september budapest and prague. 4th week september get to munich for octoberfest spend a few days there.

i really wanted to see interlaken, gimmenwald, hallstat, krakow, warsaw.

im thinking of cutting sicily out and save that week and train time and then maybe i could see the above cities. ive gone through the various passes and it looks like the top of the line eurail pass will have to do even though eastern europe is pretty cheap as is spain and portugal and it practically will be a waste those 3 weeks greece island hopping. lots of information i know but any input would be great.
