I have a 3 night upcoming award stay at a SLH property. Decided to extend it by a night and didn't have enough points (especially since Hilton raised the point requirement since the original booking) so paid cash for the extra night. Had a lot of HH points post from Amex and topped those off with the Points purchase bonus sale to have enough. Canceled the cash reservation a week ago and the base room still isn't showing as available on Hilton, yet the SLH hotel page shows 2 rooms available.
