Hilton HHonors members can earn double points on all nights or a free night certificate after four stays or 10 nights through Dec. 31, 2011. Registration in the Fast Ways promotion is required at HHonors.com/FastWays and you must choose one of the two offers prior to check-in.
Once you make your selection, you cannot change it so consider your upcoming travel plans before registering. There is no limit to the number of free nights you can earn. Not every Hilton hotel is participating in the promotion. You can view the hotels not participating at http://www.insideflyer.com/link/?5349
Bottom line: If you will be completing less than four stays or 10 nights, we suggest you pick double points–this might be especially beneficial if you have long, expensive hotel stays planned. But if you think you’ll have more than four stays or 10 nights, it may be a better deal to choose free nights, especially if you have travel coming up in the next few months. The free night certificates can be redeemed at any participating hotel or resort in the Hilton Worldwide portfolio and are valid for six months from the date they are issued.
