Hi the Golden West is a wonderful holiday, even better if you have Ann Murray as your tour manager. San Francisco was brilliant - so atmospheric with the Golden Gate Bridge, Alcatraz, the cable cars, Chinatown and brilliant views. Lovely drive along Highway 101 down the coast. Santa Barbara and Long Beach two great stop off points and Palm Springs has great character. It was great to see Hollywood and other iconic areas in LA. As for Vegas - I didn't think I would like it, but I absoultely loved it! The variety and originality in the different hotels was incredible and of course, to top it all, the Grand Canyon was breath-taking.
Unlike many others Route 66 does not appeal much to me, apart from the beginning and end - Chicago and LA. So I'd say go for the Golden West, but have a brilliant holiday whatever you decide!
best wishes,
Bob
