Has anyone here ever taken the overnight train from Paris to Venice? I am debating on whether I should do this, or fly via easyjet. I know the cost comparisons and tricks to using the tvg-europe site, so basically it comes down to comfort at this point, not cost. If we book the double sleeper (it's just my husband and I going) - will we sleep comfortably? Does the train 'rock and roll' all night and keep you awake? They say they are air conditioned, is this true? I think the IDEA Of a night train makes more sense if you wake up rested for Venice early the next day... however, I am leery of it not being as good of an experience as it sounds, staying up all night, not sleeping and being walking zombies the next day. Any experiences from you guys?
