Just booked a 4-night stay for 6/19. The only 4* LAX hotel ($80) got me the Westin. It's listed here as 3.5*, so be aware if you are planning on getting a room at the Sheraton Gateway. :) Perhaps I did something wrong? Haven't booked with Hotwire for a while. Noticed here that it used to be a 4* though, so maybe they switched it back?
