It was my first show so I can't compare to others. I bought a Canvas of JFK
in the 1970's with a few European Heavies. They had a bunch of models-- Gemini Jets, Dragon, Herpa etc. They had FSX set up (all default stuff) with a yoke, peddles and throttle. I was able to fly around while kids stood behind me waiting their turn. Lots of miscellaneous items such as dishware, key chains etc.
I did not go on any of the tours because, honestly, I've been in aviation and worked for C5 so its all old hat for me, although I think the Tower tour would've been neat.
