@PolyAddict I've been watching the prices for S/D for Feb 2020 since they were released, they have not gone down. There appears to be some type of large conference at the Dolphin. Rooms are running full price. The discounts will probably come when those rooms are released back to the hotel for booking, 60 days is generally a good rule of thumb. But the large conference I'm going to in July 17 just released rooms back on June 26th. I was able to move from the conference hotel to another right next door and save some $.
As much as I wanted to stay at S/D for our Feb 2020 trip I decided to book at POFQ as I just couldn't see paying $400-500 a night. With the increase in point values using my points there didn't make sense either. Time will tell if they are able to fill the rooms for the conference and/or Galaxy's Edge. If you can wait to see if prices drop you might be in a good position.
