Ass in a chair, toes in the sand.
"…I once found a list of diseases as yet unclassified by medical science, and among these there occurred the word Islomania, which was described as a rare but by no means unknown affliction of spirit. There are people…who find islands somehow irresistible. The mere knowledge that they are on an island, a little world surrounded by the sea, fills them with an indescribable intoxication. These born “islomanes”…are direct descendents of the Atlanteans." - Lawrence Durrell
