I have received a late room at Boulder Ridge. This was before 2020, so it was not due to recent staffing levels.
Really, though, any of them can have that issue because a lot of it is due to how many rooms are turning over that day, and how quickly the departing guests leave their rooms. Villas take a while to clean, and if you happen to be checking in on a day when a large percentage of rooms are turning over AND a lot of those rooms were occupied until the very last moment, you may have to wait.
