Hello,
My friends and I are traveling around Europe for the summer with eurail pass (10days in 2 months). But after we bought the passes, we realized the seats for pass holders traveling from London to Amsterdam are perhaps sold out (shown as price unavailable). We therefore decided to travel to Amsterdam by flight and exchange the ticket to 7 days in 1 month. I’d like to ask
1. do we have to wait for the completion of exchange process before marking reservations?
2. some previously shown as “no reservation required” are now “details unavailable”, do we need not to make reservation and hop onto the train as we arrive at the stations?
Any help would we appreciated.
