I’ve been checking frequently and the discounts look pretty random almost like they were on accident. I was able to get a good deal on Portofino, which was the only premier hotel to have an AP discount (and cheaper then the others by 150 a night ) and then I was able to get a 2 bedroom suite at endless for slightly cheaper then a normal room. However, looking at the discounts a couple days after I booked, it seems like they both disappeared.
