Yes! My husband and I just went on our honeymoon in January and had a special offer of “Save up to 30% on 5 night stays, Plus book early and get a $50 report credit per night.” It was valid for stays January 6 to March 22.
Looks like you had to book by October 3 to “book early” and get that credit.
I will say, for a January trip we were really surprised how late in 2018 it was before we could actually book, so keep your eyes open!
