Always wondered about the name.
...Roosevelt maintained the air of mystery by sharing none of the operational details of the attack, and quipped to reporters that the raid was launched “from our new secret base at Shangri-La.”

Nomenclature
The naming of the ship was a radical departure from the general practice of the time, which was to name aircraft carriers after battles or previous US Navy ships. After the Doolittle Raid, launched from theHornet, President Roosevelt answered a reporter’s question by saying that the raid had been launched from “Shangri-La”, the fictional faraway land of theJames Hilton novel Lost Horizon.
I believe Camp David was originally called Shangri-La (after the fictitious place in the novel) by FDR, but I don’t know if he had started using that name before the raid. Eisenhower renamed it in honor of his grandson.
