This is a very nice old key from the long gone King's Castle. I never stayed there and only gambled there once. It was a pretty nice place and the "old England theme" was really over the top. I loved the way they announced phone calls - it was well before cell phones - if I had a call they would say "Call for Sir Charles of Davis" - not that I ever got a call. It opened in 1969 and became the Hyatt in 1976 and the Hyatt Regency in1990.
