Hi,I have renew my passport after the booking. i have been told that i need to do my passport detail amendment in the station by one of the staff, but i have not been told which station to go. I am travelling from Paris to Rome by Thello. Should i do it at Paris-Gare-De-Lyon station prior to my travel or can i do it anywhere in Uk? Can i bring my old passport with me during my travel instead of amend the detail?Thanks.
