If you want "near the conference" you might be outta luck. There's the crown plaza that's in the same clump (at least, if we're thinking of the same con center and hyatt- the Hyatt is right across the street and has a skybridge) that I think is a bit cheaper but not as nice.
There are other hotels a bit farther out for sure, but I only know the ones in walking distance of the Donald E. Stephenson.
