I want people to be able to book the whole hostel easily

Good afternoon,

I own a hostel with 5 private rooms, one 4-person dorm and one 10-person dorm. 
Now I would like to rent out the whole house as well. 

Is that possible? Now guests have to book ALL the rooms and dorms before they can rent the whole house, which is not practical. Also, I want to offer a different price if someone would want to rent the whole house.
