Truthfully considering there's only 25 ish students in the academy compared to its usually presumed high number.  A lot of people probably got rooms to themselves...

Not as likely as you'd think if you count rooms on the pictures supplied on the OP. 

EDIT: Eh apparently there's enough rooms for 11 males and 11 females (not counting those in the subbasement as I consider them reserved for the X-Men). So Pretty much everyone could have their rooms.
