Its all spelled out in the rules document.
Use of Accommodations by HGV.
Beginning the first day of the Open Season reservation window, Hilton Grand Vacations reserves the right to utilize accommodations for its own purposes including for exchange, inspection visits, promotions, rentals, special programs, or any other purposes in Hilton Grand Vacations’ sole discretion . Additionally, when a Member exchanges their ClubPoints for benefits or services other than Affiliated Resort accommodations, such as ClubPartner Perk reservations or Honors points, Hilton Grand Vacations must pay the third party for the Member’s use thereof . As such, Hilton Grand Vacations, in its sole discretion, may rent or otherwise use the accommodations relinquished by that Member or other unused inventory to cover the cost of such third party benefits and services . In renting accommodations as described herein, HGV may use historical reservation data for the property to forecast the accommodations projected to remain unused by Club Members or to be used by Club Members for other benefits and services requiring monetization by HGVC and rent such accommodations prior to the start of the Open Season reservation window in order to maximize occupancy levels at the property .
Additionally, inventory owned by a developer or an affiliated resort and not yet sold, may be made available for reservation by Members or used by the developer for any purpose including but not limited to, exchange, rental, Elite privileges and promotional purposes .
