If that's the case, you should definitely try to hoodwink the Four Points into giving you the $45 crew rate. The shuttles come every 20 minutes, and it's less than 10 minutes from the airport...and the rooms are pretty nice.
If you're not opposed to sleeping on a floor, I'd get a neck pillow and head for terminal 2. There's an E-F gate connector that is private compared to the rest of the place and people crash there all the time.
