From Hilton HHonors® FAQs for Owners (from 2005)

How am I reimbursed for reward stays?
Each hotel is reimbursed for any reward stay accepted. The amount is determined by a monthly threshold of rooms, which is calculated by computing the number of rooms at your property X 30 days X 1.8%. This number is your threshold number of rooms per month. For months in which the number of reward rooms taken as a percentage of available rooms is less than or equal to 1.8%, you will receive a base rate (determined by brand, see below) plus tax for all reward nights (excluding rewards taken on sellout nights). For months in which the number of reward rooms taken as a percentage of available rooms exceeds 1.8%, you will receive 90% of your [prior years] annualized ADR plus tax for all reward nights taken above the 1.8% threshold (with the exception of rewards taken on sellout nights). On nights when your occupied revenue rooms occupancy is at or above 96.0%, you will receive 90% of that day’s gross ADR plus tax for all HHonors rewards taken that night regardless of whether you are above or below the 1.8% threshold. For a new property, your forecasted ADR will be used.

What is the minimum reimbursement (base rate) for each brand?
$15 for Hampton, Scandic and Hilton Garden Inn
$20 for Doubletree, Embassy and Homewood
$30 for Hilton (worldwide) and Conrad

NB: New versions: This amount varies by brand.

Where does my money go?
HHonors fees collected from the hotels cover the Points & Miles issued, Hotel Rewards and program liability - basically all the consumer facing expenses. This equates to approximately 75% of total program cost. The remaining 25% is funded by Strategic Partner Revenue (contribution or revenue from our partner relationships, i.e. Co-branded credit cards such as the HHonors Platinum Credit Card from American Express). This remaining 25% fully covers the administrative costs of the program.
