I’m amazed. The Hotel California answer (“colitas”) talks about possible origins and meanings of the song, but makes no mention of Sartre’s “Huit-Clos” (the play translated as “No Exit” in English). “Hotel California” even matches the initials of the play’s original (French) name.
In the play three people are checked into a room in a hotel only to eventually find out that, not only are they unable to leave, they are in Hell. It turns out that each of the three was selected to provide that special hellish environment for the other two. Everybody hates everybody, and at one point one of the characters even attempts to kill another with a letter opener. (“Stabbed him with the steely knife, but you just can’t kill the beast.”) Of course, that’s before the characters realized they were already dead. Seems to me (it’s been nearly 20 years since I read it), there was a trouble with getting something to drink from room service, too. But I could be wrong about that one.
