I would say any glass elevator in a Hyattesque atrium hotel or free standing tower. There are just too many to mention. The most impressive one I have seen would be the Marriott Marquis's in Atlanta. Wow!!! I have been in the Westin Bonaventure a few times and would say it's not one of John Portman's finest. He's the architect of many of these types of hotels. The movie "Nick of Time" also had many scenes in the hotel. There was also an early Michael J. Fox movie which I think was named "the allnighter" or something like it that had the ending at the hotel. Violist, I believe that the new Detroit mid-field terminal will have Otis designed horizontal elevator people mover contraptions. I think the weirdest elevator I have been in was at the Dublin Hilton. It was extremely long and narrow and had a LCD monitor. Very strange.
