I've just done the very same in Germany with 3 paid stays all on same room type.
I made sure that the hotel were aware of my multiple reservations when I first checked in, they allocated me the same room for all three so I wouldn't have to move about, but I insisted on paying the invoice for each reservation as it completed rather than them being "carried over" onto one combined invoice for my whole stay.
I now always do this as it ensures that the points and qualifying nights are correct for each reservation as the first ones otherwise tend to come through as non-qualifying nights with no points and then the final one posts with points for the whole value for all of the nights but only the qualifying nights for that reservation. By keeping them separate they're always correct and I don't need to keep submitting missing points/nights claims to IHG.
