I’m travelling back to England from France on the 5.50pm sailing P&O ferry Calais > Dover on Wednesday 25th June. On our last day we’re planning to visit a couple of WW1 memorials on the way from Reims to Calais. I like to maximise the amount of time we spend at these sites, but don’t want to cut it too fine arriving at Calais.
The P&O booking info says we have to book in at least 30 minutes before the sailing time. However they don’t give any indication of the likely time we need to leave between arriving at the terminal and getting booked in.
What is the latest we should be able to sensibly leave it before we need to get to the Calais ferry terminal?
