welcome to ft. you are trying to crowd too much into 14 days. just rome, florence and paris are reasonable. adding umbria, tuscany, cinque terra, geona, versallie, one or two small towns, and a kitchen sink puts you on a train or bus for the whole trip. if you are young, plan to return. skip most of that stuff, and spend 2 or 3 quality days in each place. save the big cities for when you are old. at least we did. now that we are old, we go to paris, london, venice rome, etc. for the first 20 years when we were strong, we did countryside.

can you drive? driving in italy is really not that bad. the cars are very nice, and the auto routes are much better than the us interstate system(anything is better thanI95)

each one of those moves i listed eats most of a whole day. that's 10 days.

for specifics, i don't think the train goes to umbria. you do not see anything worth seeing of tuscany from the train. i don't think you can train to cinque terra(not sure).

once took a night train from paris to milan. the train went west of the alps, and saw nothing. have done more than a few trains in italy. never saw anything worth seeing. looks like maryland and new jersy.

consider an open jaw from rome to milan, get a car and drive to small towns. small towns in both italy and france are wonderful and inexpensive. the people are fabulous. or, you can start in nice and drive to paris, stopping at 10-14 small towns along the way. do not drive in paris or rome

what is the space outlet. this some place that sells space on the cheap? or did you misspell spice?
