I wouldn't worry about your dorm placement. When you submit your housing application, you can't select a particular dorm -- just modern or traditional and then single, double or triple. My son (a freshman) ended up with his last choice (traditional triple) and was initially very upset, but his feelings changed immediately after he arrived and now he couldn't be happier. (By the way, he's in Beaumont, and -- contrary to FHN-dent's view -- he insists its the very best freshman dorm. He plans to stay in a traditional next year.)
My son really wanted a modern dorm, and now he thinks they're sterile and stodgy. But if you talk to someone living in a modern (like FHN-dent), they will say just the opposite.
The moral of the story: Don't fret too much about ranking your preferences, because ultimately they may be meaningless. The South 40 is a great place to live, whether you're in a traditional or modern. A year from now, you're likely to be a partisan advocate for whichever dorm you're assigned to.
