You won't have any subsidization for hostel during holiday, that is, you only have that $1,040 per semester for your term stay. If you want to stay over holiday here, you must pay yourself the holiday stay fee. If you clear out everything, you won't need to pay a single cent. Normally, they pay several dollars to put their stuff in store room.
