Hi, I want to book a reservation from Paris to Frankfurt (the first train of my trip...) but when I go on the websites it says the prices are unavailable at the moment and I should try later. The weird thing is that when I connect with another navigator it shows me the price (13€) but an error occurs when I want to proceed to payment.
Do you know if that means the train is full ? Can I buy a ticket in a station instead ?
Thank you
