This hotel is one of the worst I have ever stayed in my 30 years of work travel. When i was delayed yesterday, i called to make sure my reservations were not going to be dropped given my midnight arrival. They say ok. However, when i get here, i am assigned a room in a tower away from the lobby, given a map, and sent out on a darkened path with no lights on the signage. Finally i get to my room, go into the space where the light at the bedside is out, and when i look out, i see the parking deck. 3000 miles and i get the room by the elevator that goes up and down all night. Wake up this morning to see black mold looking marks to the ceiling. Go to my conference, walk ouside and perch on a wall (no signage) and get told i am blocking the view.
