Closest thing to GF is going to be the Grand Californian. There are many many off site options. Fairfield Inn and Hojo are the nicest of the motels across the street, about a 8-10 minute walk to the gate, but they are essentially upscale motels not true hotels.
Slightly farther out the conventon center hotels (Hilton, Marriott, and I think Embassy Suites?) Are a farther walk, ~20ish to the gates (DL ppl consider that loooong) but are nicer and live up to their brand names. Not sure if the sheratons are walkable since I haven't stayed there.
HTH.
