I looked at there were site while they did mention Modern games i didn't see a DDR mentioned. maybe they could wall off there Indoor Gold and replace a section of it with a DDR area.
I think over all there trying to keep in business they are the second largest arcade in the Country and that takes money to keep up. I think it would be smart of theme to put in a small indoor amusement park a few family rides and a coaster or two. they'd get more money and it would give people a reason to travel to them. I'm sure most people would play a game or to and get some food.
