I had another post earlier - flight has been cancelled and am trying to get to Italy. I've worked out a route that includes a sleeper train from Paris to Nice, but in a 6-berth couchette. I'd be too frightened to sleep with 2 random strangers in there as well as my family, so am thinking if I say the party is of 6 people we can have the whole thing (and just buy 6 tickets). but this means inventing 2 fake children - am worried there might be issues with this. anyone know?
