Looks like the Normandie is being taken out of service for a few days 18/06 to 23/06. So it will effect those travelling back from the Tuesday onwards.
Doesn't effect us as we are going via Le Havre, although they did alter our timings a tad.
May be that they need to do some work on the Normandie, it was due to be replaced by the Honfleur in July but that isn't going to happen any time soon.
