should be no problem -- when you check in for the first night explain that you have two rates/reservations. They should be able to combine them and let you stay in the same room for the whole stay -- I have done this several times. Then again you might try checking out and back in on the second reservation and you might get away with it for the Stay Free, but i would doubt.
