There doesn't seem to be much of an off-season here anymore and hotel prices border ridiculous, but you can still get the Delano at $400 which is an ok deal. I just checked for next week and they show $400 rates, but that's for midweek ..... I like the Delano best because it has a really nice vibe but no way that $790 is justified unless you are getting something like the penthouse.
You may then stick with your first choice, the Setai. Rooms at the Setai should be better than at the Delano. Setai at $595 is most definitely a better value than Raleigh at $525.
Setai are running a couple of Rangerovers as shuttle for their guests, they might pick you up at the airport (not sure about that, though).
