Hello community,

We'll be travelling from central Finland to southern France late September and coming back late October. Two adults and two teenagers. Here is a more detailed plan at the moment:

27th September train to Turku (buying regular tickets well in advance)

27th-28th a Viking Line night ferry from Turku to Stockholm (buying regular tickets as the Interrail discount seems to apply only to day-time ferries, at least on our travel date if I'm correct)

28th September train from Stockholm to Copenhagen (using the first pass day and thus starting the validity of the pass)

night in Copenhagen

29th September train from Copenhagen to Berlin (2nd pass day)

night in Berlin

30th September nighjet from Berlin to Paris (3rd pass day, when will the couchette/sleeper tickets become available?)

night in Paris

2nd October train from Paris to Antibes (4th pass day, preferably a direct TGV, where to get seat reservations and when will they become available?)

24th October train from Antibes to Genoa and a nightjet from Genoa to Munich (5th pass day)

25th October train from Munich to Travemünde (6th pass day)

25th-27th Finnlines ferry from Travemünde to Helsinki (tickets already bought during a recent sale)

27th train from Helsinki to Jyväskylä (7th pass day and the last day of the validity, do we need seat reservations and if yes, how to get them?)

Does all of this sound reasonable? If yes, we are planning on buying two adult and two youth passes (7 days in a month) during the current sale. Any comments and suggestions would be appreciated!
