Hi there,
This is the 1st time I am posting query in this community and so please bear with me. I will be travelling with my family to a few destinations in late Apr/early May, with global pass. We are planning to travel between Paris > London > Brussel and I understand I have to make seat reservation in advance for taking the Eurostar. My question is do I have to activate my pass (I have added passenger details into the app but have not activate) in order for me to make the reservation online? As I have never try online seat reservation, plus I understand that there will be a fee incurred if there is a need to rescheulde my train timing after making seat reservation, hence I need to understand in depth instead of doing something silly.
Appreicate your guideline in this matter.
Thank you.
