Hello,
I am planning to upgrade my Eurail pass from 7 days to 10 days as I have added on some travel plans. I will be going in late August/early September, so I have no yet activated the pass. However I booked two seat reservations from Paris to London, and London to Brussels (both on the Eurostar). Will I believe to keep these seat reservations on my new pass?
Thank you for any help you can offer.
