As long as you are in possession of your pass on the day of travel, it is not necessary to validate it first.
CHEAPER normal tickets (update by SiDUDe):
If you can book in advance you can usually find much cheaper advanced normal tickets, sometimes as low as half the pass holder price for a return, although you have to commit to specific trains on specific days
Avoid the EUROSTAR - use a ferry:
FRANCE (Calais) - UK (Dover): paris-london-ferry-calais-dover-t1442.html
NETHERLANDS (Hoek van Holland) - UK (Harwich): ferry-netherlands-england-t1659.html
Due to the unclear situation of the ferry prices, think about using a bus (also overnight): https://en.rail.cc/train-connec ... kingdom/70
