They may not expect you to have checked bags anyway if it's just an overnight or two so I wouldn't bring that up. As the others have said, take what they book for you and then figure out how to get points from it. I lucked out and rescued a bunch of DL points from expiring once when a prospective employer booked me on DL. (Of course, now that I'm on FT, I know other ways to keep accounts active!)
