<p>Curmudgeon - she is struggling with getting clear info on this, as are others if you look at the Dartmouth board, so take what I'm going to say with a grain of salt - Sybbie jump in at any time. What I said is related more to the situation at Dartmouth, particularly.</p>
<p>A lot of the angst is specific to Dartmouth - remember with the D-plan, during soph and junior years everyone moves on and off campus, so you might have 3 or 4 different living situations during those 2 years, rather than the 2 living situations taht would be normal at most colleges - you need to meet as many people as possible. If one of the freshman dorms becomes sub-free, that would be ideal, some floors are listed as sub-free on the website, but you can't request a particular dorm, just subfree.
As Idad pointed out, there are some opportunities for mentoring, etc, in mixed class living, but I think it is also possible that the upperclassmen have made their circle of friends, know they want the quiet dorm, and want it to stay quiet (not perhaps a good situation for making new friends), also they may only be around for 1 term. I think the mixed class system works well at Swarthmore because almost all the housing has frosh mixed in - the sophs are the ones who are a little more segregated, because of lottery numbers. At Dartmouth half the frosh live together, the other half are in mixed housing.
There is a 3rd option that Sybbie's daughter lived in, I don't think it is officially substance free, but it is de facto low substance, which is probably what we really want for our kids. But, jump in here Sybbie, neither her daughter nor the roommate elected to live there next year.</p>
<p>If DD was going to a school where she could actually request specific dorms, I think she would go for a sub free freshman dorm. Since she is the fatalistic type, I think she is leaning toward taking her chances in the general pool. I'm staying out of this decision as much as possible. I hope she is going to go to the 09 website and the LiveJournal to get ideas about what others are doing - again since Dart is basically on quarters, she hasn't even gotten her housing forms yet.</p>
