What’s Eagles ‘ Hotel California really about?

What’s the famous song of the late 70’s is « Hotel California » really about, according to Eagle’s Don Fedler (from Wikipedia):

« Don Henley and Glenn wrote most of the words. All of us kind of drove into L.A. at night. Nobody was from California, and if you drive into L.A. at night… you can just see this glow on the horizon of lights, and the images that start running through your head of Hollywood and all the dreams that you have, and so it was kind of about that… what we started writing the song about. Coming into L.A…. and from that ‘Life in the Fast Lane’ came out of it, and ‘Wasted Time’ and a bunch of other songs. »
