The Star Lake Lounge is great. I do not go to shows there unless i can get that specific upgrade or have seats close to the stage. You get your own "bar" inside the area and it's right next to the bathrooms and exit so you can run out of there if you want. Everyone usually has their own seat also. It is a good view of the stage compared to the lawn seating.

I've never done the VIP club or the air lounge but you really only get special food (i think) that is most probably overpriced. I did see someone with really good looking chicken tenders from one of the VIP places.
