A historic residence in LA torn down in 94'. Not a Hotel proper. It's a song by the Eagles with encrypted and well crafted messages using metaphor and play on words etc to convey a 1969 tragic event in such a way that only certain enlightened listeners can understand.
The Hotel on us in exchange for snitch money and this occurred in California. Eagles did not want to use La La Land to pin down the location and risk linking the incident to other artists who referenced the same historic event referred to as the Hotel California.
