Ok I think, there are airports in Orkney and airports in London and various other places on the way. I'll do some research and see how much it will cost to drive to Orkney, then leave the car for someone else to bring back while I fly to the likely event site.
Cue a jaw-on-floor moment. I could fly half-way to Australia for the £300 price of a Kirkwall to London flight, or save about £50 by flying to Scotland then taking a 6-8 hour train journey to London.
Just how much do I love LRP...?
