Would appreciate your advice about this trip
Family of 4 (2 adults, 17 yo, 13 yo) none of us have interrailed before. Current plan is
3/8/24 Eurostar to Paris (know we need to reserve seats - is it ok to have bought just one pass beforehand and use just one pass number to reserve seats?)
7/8/24 Paris - Barcelona
12.-13/8/24 Barcelona to Florence - was thinking about an overnight stop at Nice?
18/8/24 overnight train Florence to Salzburg
21/8/24 Salzburg to Cologne
23/8/24 Cologne to Brussels
25/8/25 Eurostar Brussels to London
Our only fixed point at present is Paris as we have accommodation booked to see some of Olympics but I’m keen to book other accommodation as it’s the summer season
Any advice on the trip/ trains/booking much appreciated
