On the interrail.eu reservations book reservations page, it seems that every single service to Cherbourg from Paris has no availability. I understand that some may be fully booked, but given even the very early morning ones far in advance say no availability, I suspect the system might be broken from the recent update that reservations are now mandatory 7 days a week?
I have also heard that it is possible to buy seat reservations at a ticket machine when we are there, but I am worried the train may have booked out by then?
Any advice or tips would be appreciated!
