I am planning a trip in May. I will be most likely be using a Mirage offer, but would like to spend one night at Caesars to give it a try. This will, depending on how stuff works out, either be the 3rd or 4th night of my stay. My concern is that if I don’t book know, the Augustus tower won’t be available as a comp when I’m finally ready to book. If I booked both nights now, could I cancel just one night, or does the entire reservation have to be cancelled and rebooked. Anyone have any experience with this?
