Anyone who stayed after Jan 18, but especially who booked after Jan 18, please read this Deals We Like (Boarding Area) blog:
Didn't Receive your Wyndham Points? Now you Can! - Deals We Like
It says that WR offered people who read that blog an email to use to request credit even if they booked after Jan 18. (People who booked before Jan 18 shouldn't need to request anything, just wait.) So read carefully and follow the directions there, and good luck!
