OK with the epic fail of 1st video uploading to YT right of these elevators, here is my 2nd attempt. I reprocessed the video through Corel software in case for some reason the first file was corrupt even though it played through fine on my computer before I uploaded it. I'm not sure if the problem occured in uploading to YT or if the problem was something in the mixing process in the Corel software. In any case, this was a nice hotel to explore. The elevators were Otis but had Dover phone button.
