Well I had just put the finishing touches to persuading the wife that she didn't really want to visit Aberdeen on test weekend after all (costing one airline ticket), and booking Speedferries (costing a return ticket) just to ensure that my tickets were on time and surprise surpise - they have turned up in the post... UPS man apparently wanted a signtaure but lucky timing meant my daughter was there to do the deed.
So I have either a useless flight to Aberdeen (use it or lose it, but can be altered for £30 I think) or a useless ferry ticket.
I expect I will go to Test, as I've already been through the grief barrier about cancelling her little holiday...
