I used to like the Holiday Inn on Century - OK
, its a bit further out (almost at the 405) and not the most elegant of hotels, BUT the price was always fair and the rooms had dual SLIDE OPEN windows from floor to ceiling with a very small balcony... No views of the south side or the airport, just the north side approach. However, it was fun to lounge in a chair with a gentle breeze coming in, coffee or room service, just waiting for the landings to swish past. With a north facing room on the top floor and a 400mm lens, this sort of picture was entirely possible:

However, the Holiday Inn is undergoing a major refurb at the moment and whether the slide open windows remain will be interesting to see...
The other hotel I used to use was the Renaissance... Not so much spending time in the rooms (slide open windows are fastened shut with screws), but the top floor of their parking garage. I understand that they've become quite anti- there now, but even so on one time the duty manager came up and told me I had to leave the garage, and I said that as I was staying at the hotel (guest pass in hand) and had a car parked on the roof, I had no intention of leaving. YMMV.
Of course, it was difficult to beat the roof of the Radisson, but that seems to be still lost to us for now!
None of the other major hotels seem to have both views and opening windows. These days therefore, I tend to take whatever hotel is competitively priced, and make do with Imperial Hill and In-N-Out!
