Dress aside, what will there be to interest a member of the public who can't stretch to a private A380? Not to mention my girlfriend. We've both got tickets for the Friday already.
I was assuming, rightly or wrongly, that there wouldn't be much in the way of GA specific stands, which is fine. I guess I'm worrying about wasting my time and the time of exhibitors, who at the end of the day are there to sell stuff to people with money - not to not sell stuff to people who don't have money.
I shall probably not wear a suit, to avoid giving out misleading signals.
