We were at both places on the same trip but honestly I was more interested in Disneyland and Knott's Berry Farm

I'll ask
Jim Edwards who was the curator of Harrah's (plus being a P-51 ace and 150 mission Typhoon pilot

). Jim BTW should be in the warbird hall of fame for saving so many vintage a/c like the P-38, P-40M, Tri Motor ect ect ect
