im catching a tgv from paris to geneva 29th June. it says booking is required. i tried to book but it seems to be fully booked.
It says "Prices unavailable. No price results were found for this connection. It is possible that all pass holder seats are sold out. Please try searching for another connection or check 'More information' and try other ways to book this seat reservation. If no pass holder seats are available anymore you need to buy a separate full fare ticket to board."
Am i allowed to stand or sit on the train floor without a seat reservation. All the trains for the day say the same thing.
I tried booking on other train sites and all say fully booked or don't give option.
If I have an eu rail pass can I use that amd just stand on the tgv train, or is a seat reservation essential?
