I'm planning to get on the calidonian Sleeper at 22.22pm on the 16th at April at my local train station in Garelochhead for the start of our interrail tour.
I have paid for the room supplement, great.
However as this is my First journey of the day and the Calidonian sleeper only need a ticket valid on arrival so the 17th... is the correct? Or do I just need my ticket to be valid in the app for the 16th?
I also read somewhere they said to add it manually but I can't work out how.
Any assistance would be very much appreciated!
