I've been here as there are fingers on my hand and it's a pretty decent arena. If you're in the way way back seats of course it sucks so shoot for mid-level: you'll still feel like you can touch the performers' leg or at least know you're breathing the same air. There are two large screens on either side of the main stage so you don't necessarily miss the action or feel like you're watching a flea circus.
The spaces between the rows are fairly decent however I'm a petite lil thing so space is never really an issue-unless you're violating it. The stairs aren't super scary or steep too so gals in stilettos: don't be too afraid.
There was plenty of bathroom stalls and concession stands as well. You can even even rent binoculars!
