I am divided, I love the terrain and atmosphere of sky high, but dislike the smell of the potties and the lack of power at all of the awesome places to setup camp is slightly irritating. I love the vast extent of the explorable area, though my calves usually complain something fierce post event.
I like the Magic Sky site because I get to interact with so many more people with the guild in the town hall, but there is no middle ground with the lighting. It's either full blast or pitch black. I also cannot reach this site in my own car, which is troublesome.
MmR was cute and had a lovely drive to get there, but just seems inescapably damp. And doesn't have a great central area for field battles. It seems I dislike this site a lot less than most people.
