On stay - yes basically you are right, it was the front desk that asked me on my departure time, and based on that, proactively offered me the breakfast move. I think they have their fair share of stop/layover guests experience to be able to ask these during check-in. It's also a probably good way to utilize unsold rooms (guessing during peak season, it will be harder to get such flexibility).
