I tried searching the forum but didnt see an answer to this question: how long of a train ride is Nice to Rome and is it worth it to do it in the day to see scenery or just make a night trip out of it? I have a Eurail pass so I prefer train to flying unless flying is supercheap.

Also, side note: if I am going to be in Paris from a Monday to a Friday, what is my best option of metro pass? week long? 10 day? Does that pass cover a trip to Versailles?(I’m note really sure how it works) and also is it worth it to get a museum pass?

Thanks all!
