You must have your SkyMiles membership number saved to your Starwood Preferred Guest profile in order to receive SkyMiles in lieu of Starpoints — otherwise, the bonus will be awarded in Starpoints. Bonuses earned from eligible room rate bookings will be converted automatically into SkyMiles; will be credited to your Delta Air Lines SkyMiles frequent flier loyalty program account and may not be transferred back to your Starwood Preferred Guest account.
Earnings from this promotion are in addition to what you would earn through the Crossover Rewards partnership between the Delta Air Lines SkyMiles and Starwood Preferred Guest frequent travel loyalty programs if you have already earned elite level status.
For this fairly simple promotion, an eligible stay is defined as two or more consecutive nights paying a qualifying rate in the same participating hotel property — regardless of the number of times you check in or check out. You must be a member of the Starwood Preferred Guest program to be awarded bonus SkyMiles.
I have not found a list of participating hotel properties at this time.
Rates are per room, per night, based on single or double occupancy, and availability at the time you book your reservation; and do not include additional per room or per night charges which may be imposed or state and local taxes.
A limited number of rooms may be available at these rates. Blackout dates and other restrictions may apply. This offer is not applicable to groups; and it cannot be combined with other offers or promotions.
