I grew up in Burbank, San Fernando Valley (just over the hill from Hollywood). The Marriott Hotel across from the Hollywood - Burbank Airport ( now called the Bob Hope Airport ) is nice, clean & in a better part of the L.A. area - at least it was when I was last there in 2002 . Lots of things to see in that area also - Disney Studios, Warner Brothers Studios, Universal Studios, Columbia Studios. Grew up just North of Columbia Studios & used to play in all of the various Studio's Back-Lots.
If you like old Trains, then Travel Town on Forest Lawn Drive is a "must see". There's also the L.A. Zoo close by; and the Griffith Park Observatory on the Hollywood side of the mountain - can be reached from BOTH sides by driving through Griffith Park. If you like Horseback Riding there's Pickwick Stables in Burbank -(Horse Rentals)- and all of Griffith Park (huge) to ride in.
Lots of Museums & Cultural Centers in L.A.; Grauman's Chinese Theatre in Hollywood; Hollywood Boulevard (trashy); Disneyland in Anaheim; Knott's Berry Farm in Buena Park; etc.,etc.,etc. .
I could list more places than this site would allow me to post. LOL! Doc :>)
