Caesars 5000 point free night awards question
 

Hi, I've earned 2 of the 5K point free night awards (as I've crossed 10K in tier points). As I can get free rooms comp'd any time I go to Vegas under normal circumstances, does anyone know if I can book these two free nights for someone else or do I have to be on the reservation and check in to the hotel? Want to give them to a family member, but won't be with them for the trip. Thanks!
