Just had the phonecall from mum saying her appointment is through, she's seeing the specialist tomorrow afternoon for an intake consult. Some frantic organisation for an hour, but the ferry is booked for tonight. Only booked a single for now, if the next test is within a few days I'll stay, if not I'll come back to Britain and go back next week again. She was so relieved when I rang her to say I was coming over, so I'm glad I've booked it.
I'm going over so much at the moment, that tonight's trip was paid for entirely with frequent traveller's points!
