Say you have a room booked for a week because you are doing some work at your house. Your parents or friend comes visit for a night. You book the second room right in the middle of your 7-day stay. Would your checkout of this second room trigger the IT logic and flag this as a nested stay and blow away your week-long stay? Or is IT only doing the nested stay logic when it comes to a different hotel?

I have booked a couple of rooms on various occasions when traveling with my family where a single room was not sufficient space for us. In all cases, however, I always booked both rooms for the whole stay period. I've never had the case of doing a second room for a partial and/or fully nested case. Just wondering if this would trigger a different treatment by Bonvoy.
