The cost per night is dependent upon the type of room. I would contact the front desk and/or visit their website. Sorry I don't have a better answer.
We just stayed in a bunk bed Suite it was around $530 dollars a night we had the birthday package for four people it was a great night sign up at Great Wolf Lodge and you get email deals sometimes.
Francisco is right it depends on the room and the day of the week you stay.
