MLOSs work both ways, minimum and maximum length of stays. When I was on the road all the time, any multi-night bookings started by researching the total stay and any/all combination of nights. Sometimes I found substantial rate reductions that making a couple of reservations saved me money. Most times the property would keep me in the same room, but then I always tried to book the same room type.
