My wife and I annually stay at Hyatt Place Keystone / Dillon for my work conference. The rooms and property are clean and maintained, and the staff is mostly friendly and cooperative. The hot tubs on the fifth and sixth floors offer amazing mountain views. The "free" breakfast is decent and offers a good variety. My only complaint, albeit first world, is the cable TV. The guide only shows which channels correspond with the numerics, not the programs are scheduled or being broadcast. Manual channel changing is laboriously slow due to the sluggish processing response; many are blacked out, or have no content. Beyond this, the Hyatt is a good place to stay.
