FWIW, I just got back from 3 days at the downtown Hampton inn. They upgraded me to a suite with a fireplace and bathtub whirlpool. The property seems to be pretty new and the breakfast was a good spread. I've heard that the SEA downtown hilton is a dump, and I was happy with the hampton inn at 80/night. I don't think its worth 50K points though... You should have not problem getting upgraded.
