drsausage which uni did your DD go to? Am I right in assuming she's come from Europe? I don't envy you that journey, mind you 45% of students at DD's uni come from outside of UK/EU.
We drove, splitting it up enroute so we were relaxed rather than stressed for drop off.
DD took a 100l case for clothes and packed shoes and two warm coats separately. Much to my surprise there was room for everything despite sharing a room.
Santander didn't have an appointment for DD before she left. She then realised she could submit id online, they've obviously accepted it as a card has come through here.
