Joanna's right, I did participate in the roommate notification system. This system allows you to know who your roommate is before your arrival. You can either have them choose a roommate for you (by taking a short survey), or if you know the other person's applicant number and name, you can enter that in when applying for the system. There is a section on wdwcollegeprogram.com that explains it pretty well. This system will choose the roommate that you will be sharing a ROOM with, not necessarily a whole apartment (unless you live in a 1-BR).
