also, where can i find prices on trains within france?
thanks.

if you want to stretch your railpass, take a look at the 10 days in 2 months offer. (flexi?)  that way you can buy single tickets for shorter, less expensive trips, and save your railpass for ferri discounts like this.
i found this link to france’s rail line

hope this helps

The overnight ferry passage counts as one rail day — You can choose either arrival day or departure day, so pick the one when you’re taking a train either before or after the ferry to avoid and extra day.

Here’s some useful past threads, on Greece-Italy ferries:

On the first one, oldlady has made a great list of what ferry companies to go for in which ports.

On the last thread, I never answered Nadrazi’s question, so here it is (might be useful to someone else):

Yes, you do have access to almost all of these.  They are in the public domain.  With the exception of some lounges that require a more expensive ticket, everyone has access to the pool and bar decks, the food courts, restaurants, and stores and movie theaters if there are any.

One ferry company I don’t recommend (if it is still around) is: Hellenic Mediterranean Lines.
