ADRs, Stay Length, and 180+10

I had an interesting misinterpretation of the policy yesterday, as we are staying on site for a week but changing hotels mid way through for a change of experience and a “split” stay. I have 2 separate 180 day windows, and it was explained to me that booking is very literally 180+ length of stay for each separate reservation. I found this frustrating, as I will not have any advantage booking early for the end (and most lucrative, deluxe portion) of our trip.
