I have resolved the problem with help from Hotwire and the hotel's reservation manager. The resolution took four phone calls to the hotel - two from Hotwire and two from me. Because the hotel is "oversold" supposedly, my NS rooms are just on request. But I did get the beds I wanted. No 1 double bed room for us, although hotel does have "a few of these". I would not likely have gotten this far had I got the evidence from the hotel web site and help from Hotwire. Here is what I learned, which has great relevance for other bookings. The first step, as thereuare recommended, is call Hotwire. Their customer service is great. The first agent was told the same thing I was - 1 double bed in each smoking room. She got me to Andy, the supervisor. He told me, "One double bed is not a double-occupancy room. We guarantee double occupancy". He called the hotel and got results. The hotel told him that I had always been booked in king rooms. Not likely to be true. The second step was to call the hotel to confirm the new room type. When asked about the NS rooms, the first agent said, when confronted with the web site availability evidence, "We don't give those rooms to Hotwire bookings. Those are more expensive rooms." I told her, "Do you charge more for non-smoking rooms?" "No", she replied. I asked to talk to the manager. The third step was to talk to the reservations manager, who could not have been nicer. She asked me if the rooms showing no-smoking availibility were club floor rooms. Yes, some were, but at least one of each type was not a club floor rate. After I complimented Sheraton's reputation for not discriminating against HW and PL customers, she gave me the last NS King room, a handicapped room, and requested the NS 2-double bed. From her I learned this about how Hotwire and Sheraton work. 1. On the day the booking is made by Hotwire, Sheraton is paid. They know nothing about the room request and do not then assign the rooms as non-smoking. So it makes no difference to them that Hotwire requests NS. 2. Rooms are assigned closer to arrival. It's only then that the hotel looks at the requests made by HW for room type. 3. This Sheraton does not give the 1 double bed rooms to Hotwire or Priceline guests. She was adamant that they treat all their guests the same on room assignments. 4. Hotwire can sell you a room in an overbooked hotel. This risks being walked or not getting good rooms. The upshot is that I think the hotel did try to assign us to the tiny 1 double bed smoking rooms, but Hotwire stopped this. The clerk who made this dicrimination decision probably was acting on her own and not pursuant to hotel policy. The bottom line is: you must call the hotel early and often to confirm your room requests because (1) the Hotwire NS room request may be ignored; and (2) at some hotels you may be assigned inferior rooms. I will take your advice and check-in very early, since I am staying the night before at the Hilton around the corner.
