Just wanted to add, that I emailed the Hyatt asking if I could get a non-smoking room ( told them I had a sinus allergy to smoke) and a king size be. I did inform them in the email that I did book through Hotwire and that I understood if that restricted me in room requests. They sent a reply back informing me that I would be assured a non-smoking room and if there is a room with a king size bed available on check they would put me in that room.
