As Mr Micawber might put it:
A day of classes in Aberdeen for 250 quid plus 2 nights hotel followed by a day of classes in Sunderland for 250 quid plus 2 nights hotel, result happiness.
Flight to Edinburgh £169*, amended to return from Newcastle an additional £87, 4 days car hire now dropping off at a different airport £195, cost of airport car parking now £69, result misery.
I agree to these things, I am an idiot.
*Edinburgh flight rescheduled from earlier flight hence higher cost. Still idiot.
