The building that is closest to the main building and to the big pool is the preferred area. If you look at the layout of Sports and Music, the different buildings are in a row. So, the first theme is the preffered. When you go to Movies and Pop, though, they are scattered around. The prefffered building might be a bit closer to the main pool, and it might be a tad bit closer to the main building, but in my opinion, it is not that much closer to warrant an extra ten dollars a night. The 50's also has a pool, it's just a little bit further from the main buildiing, but not enough again to make me want to pay an extra 10 dollars
