Sorry but what does 'the yielding factors ' mean?

So when I have MR in the past and they have "combined" reservations for me under one of the already existing reservation #s, how did they do that? My thoughts have always been that maybe they had the ability to "force" a room into a certain rate code if needed. So if I had two reservations A and B with consecutive stays, MR could remove both of them, and recreate a reservation under A that included all the nights for both A and B and included the same rates as before. Even if the rates we no longer "publicly" available.

No issue here, makes sense that returning a room won't necessarily send it back to the originally available rate as the hotel may have a much smaller pool of available rooms. Probably works simialarly to airlines and available seats.

lol I was afraid I'd get that question...even though the room goes immediately back into inventory you might not be able to purchase it again

2nd part first...correct

1st part - supervisors and managers in the reservation sales offices can force sell but it's extremely rare and watched extremely closely, I have received phone calls in the past from an agent in a center asking if it's ok which is more typical than the agents/supervisors/managers doing it (or for me to do it for them so my info is in the record) but if they reused one of the original confirmation numbers then I'm sure it was most likely forced but without reviewing the reservation I'm not able to tell for sure
