Hello,
I was wondering if anyone has had any luck booking a seat reservation for the Stansted Express from London Liverpool Street station. It is listed below, but I cannot seem to find anywhere that I can book a reservation and nothing on the website about the Eurail Pass (says no railpasses allowed). The reservation website comes back with an error, but I have managed to save the trip in my Rail Planner App. This will be our first trip once we have activated our passes so I have no idea if it will actually turn into a valid ticket???
