Wow a lot of people are hating on the Marquee! I was just there on monday for a kick ass show by Yellowcard and had no problems at all. And it was $20!
When you consider the other places that A LOT of these bands could be playing, and how much more YOU would be paying for tickets if they did... You should be happy to see them in a smaller setting for less than $30 most of the time. Is $5 for parking really that bad? No. Is having security check people at the door terrible? No.
I enjoy knowing that when I go to the Marquee it's close to where I live, it's almost always all ages so even teenagers can go enjoy the music the love, and I actually really appreciate that it's a no frills venue. The people running the Marquee are more focused on the music than fancy carpet or nice patio furniture and I would high five them for it if I ever meet them.
