The Marriott is connected directly to the airport. It is quite nice and, I think your best bet. No shuttles, etc. to deal with. You can walk right over. A previous poster recommended the Holiday Inn. I' d beware of that one. We stayed there several times about 5 years ago and it was OK. Nothing much but clean. Tried it last year and it was d-i-s-g-u-s-t-i-n-g! Stains everywhere, gross bathroom! Ewwwww! Unless they have done a major renovation I'd look elsewhere.
Hope this helps!
