Dont do it through the school, call the Royal on your own, and try to set up a contract independently for one semester (make sure they know you are a student). At least thats what I did. Its 750-850 per month if you are going to get a room on your own.
There is a 1000 dollar deposit which they are supposed to give you back after you move out.
Its so much easier dealing with the hotel directly, than through the school and then through the hotel.
Just my 2 cents.
