I have a hotel stay coming up over 4 nights. I booked it as three different reservations - first night cash, middle two nights points, and last night cash, each on its own reservation. I booked the same room type throughout.

Will this work out okay, and will I likely be able to stay in the same room? I did comment on the first reservation the numbers of the additional two reservations. The first and last night are pretty cheap, so I want to use cash for those if possible. If I'm having to change rooms twice, though, I'd likely just consider using up the additional points (the points value for those two cash nights would be about half-a-penny per point, which isn't horrible but isn't great.)
