Here it is:

paris to arras
arras to amsterdam
amsterdam to berlin
berlin to prague
prague to munich
munich to innsbruck
innsbruck to grindelwald
grindelwald to interlaken
interlaken to venice
venice to florence
florence to rome

I may cut out venice.

I will be flying to Athens from rome and in Greece I will pay point to point to get around. I was thinking about a 10 day eurail flexipass which sells for $781 CAD. Would it be cheaper to go totally point to point in my particular circumstance?
