Eurostar London-Paris canceled 30 minutes before. 1 short announcement: "The Eurostar at 2:22 pm is canceled. There is no more space in the following ones, we cannot exchange your tickets at the station, you are invited to book by yourself for a departure on another day. " At the counter a Eurostar agent who asks the police to drive back travelers looking for information .... a bad dream. The dedicated Eurostar line to exchange the ticket does not respond and does not give waiting time. Finally saved by the good old Sncf number which answers and reserves 5 tickets for the next day. The next day total chaos in the queue, contradictory instructions from the staff, 1h30 of queue and forced to run at the end to get the train ... in short, big no matter what.
