Just an update.

I've decided that I will fly to Barcelona on Ryan Air and just travel the coast line back to milan by train.

I have already been to Nice, and Monaco. Anybody have any suggestions for some stops on my way to Milan?

Also I know that it's cheaper to buy the tickets at the station than online but I was wondering how much cheaper they usually are so I can budget my travel out.

So I think it will look like this:

25-Nashville-Milan
26-Bergamo(Milan)
27-Barcelona
28-?
29-?
30-?
1-?
2-Milan
3-Milan-Nashville

*EDITED*
I should note that I have friend in Aix-en-provence. So I'll probably do a day in Marseille. Other than that I'm open to any suggestions.
