Yes, you are right it is/ was the Hyatt--but while I had the old name of the property wrong, the mental image I have/had is for the correct place
I also agree, speak with the manager and explain you are on a honey moon. I am blanking on his name, but he was for years, the manager of the Dan Panorama--which is where I always stay when I want to be in Jerusalem for a week.
Also, as you talk about former names, Don't forget that in a previous life the Dan Panorama was the Moriah!
