its kind of random. We had people in all kinds of roles and all kinds of locations. If I remember correctly(having a brain fart ha ha) my roommate and I were in traditions together, and my other two roommates were in another class together. You basically get told your traditions time at check in, then when you get to disney university, you get split into smaller groups. Dont worry about getting put with roommates or other people you may know, you'll get to know the people in the room with you.
