I have a reservation for the eurostar from London to Paris next Saturday. The reservation I have paid for is for the 09.24 train. However there is not a departure at that time any more, its at 09.31. The number of the 09.31 train is the same as it is on the reservation for the 09.24 train so I'm assuming they have altered the timetable. I haven't had an email. Do you think I need to do anything?
