I saw The Killers here on December 29 - the Killers themselves? Religious experience. That's how amazing they are.
It was an all GA show and the stage is on the wall at the far end of the room. While it was really easy to queue and get into the venue, it was REALLY hard to see. Most GA venues I've been in have had the stage raised higher so you can actually see the band. We were about 30 feet from the stage and I'm 5' 10" and could barely see through the crowd to the stage. They have big video monitors on the right and left which was convenient otherwise I'd just have to take the staff's word for it that it was the Killers.
Coolest part? As soon as people start jumping, the floor starts moving. Even if you didn't want to jump, you will be.
This place for a conference? A dream. It's gorgeous. A GA rock show? Not the best... but at least warmer than the pool for a New Years weekend show in Vegas :)
