Just my ha'peth of opinion, and I only use EDI about twice a year for my Orkney fix, but EDI doesn't seem bad at all compared to my local, NCL. It's a shame that they have now gone down the route followed by other UK airports (with the possible exception of Sanday) and made you take an 800-yard loop around a shopping centre before actually getting to the departures lounge, but that is an irritation rather than a serious showstopper. Like I say, I only use it infrequently but I have been through in early weekday mornings and it wasn't too bad at all.
