With the size of the Darkastle building there is no reason to not be able to take a chunk out and make a decent size lounge. Even with two mazes at HOS there was still a ton of empty space. The old ballroom would have made for nice lounge decor, but sadly that was destroyed last spring.While I would love to see DarKastle used for something better, I think a member lounge there would be cool until they can do something greater. Imagine having refreshments in a DarKastle dining room. Now, I would go for that. COS would be nice too, as others have said.
