Pre-upgrading people would make no sense if 'available' means every unsold room is up for grabs until the guest arrives at the hotel. It would also potentially create a logistical nightmare for the hotel if they blocked rooms for the day and suddenly had to start bumping people at 3pm.

So tell me what Marriott's definition of 'available' means and then the rules can be applied.
