Unless the lady likes hiking miles looking at lumps of grey metal, I'd suggest she stays at home! The partners of a couple of my mates come along and like visiting the craft fair and being invited to have a look at the pilot's joysticks

but I think the place is really something of a "boy's toys" place. A sort of aerial Top Gear!
I have always driven there so no idea of the frequency of the buses. However, I would suggest you leave before the Red Arrows if you don't want a long wait as about 50% of the crowd seem to set off home once they've displayed.
