Hello,
I recently purchased a 2nd class global eurail pass good for 7 days of travel in one month. I see I can get a special rate on the Eurostar from London to Paris with the pass. Can I buy the Eurostar ticket online at that special rate before arriving in Europe and before I validate my pass, or should I wait until I arrive in Europe and get the pass validated at the same time as I buy my ticket? The Eurostar will be my first trip using the Eurail Pass.
Thanks
