The House of Game's cabin was killer. I didn't get a chance to go into JT's cabin, or the Emerald Flame Cabin.
The pride's cabin had the lights on when I was in there. That's pretty much instant disqualification from coolness for me.
Special Shout Out to the folks in the Celestial guild. They were half tucked away and had nice walls put up, they had nice in period lighting. It might have been a secret second for niceness if you put it all together. Especially cool considering how little they play, and how much they larp other places (it must be exhausting to keep setting up cabins).
