I just completed 5 bookings. Technically I think one can make a separate booking each day and just check in and check out each day. Some hotels may let you keep the same room. I wish I had more details about my Auckland portion of OZ fest id book up the whole trip. Although one of the places I bought was just the taxes because the room was under $100.
Now I'm thinking the dumb thing I did was booked 2 day stay on a back to back MR. I should have just booked 2 different hotels since I'm not actually spending much time in the room.
