That is too cheap. $1000 is probably fair. I think you get Club 44 access, 2 drinks, a buffet, and nicer seats. The location though stinks. For me location is #1. Also for those who tailgate the buffet is useless.
I think part of the problem is the fact that we play indoors. Other stadiums having a club to go into during cold or bad weather is nice. In a Dome that benefit is gone. Also it hurts that neither Club has a view of the field. On top of that the Clubs are nowhere near the actual seats. It is a hike between the two.
