Wikipedia:Articles for deletion/List of floating islands in fiction
Looking at the above scholar references, it's clear that fictional floating islands are a notable concept.  The above deletion arguments are critiques of the content, which can be fixed by regular editing, rather than the concept.  While I agree with the critiques (floating in air != floating in water, too unreferenced, too much pop culture trivia), none of those, individually or together, justify deleting a notable topic.  Cutting it back to the Odyssey reference, or just redirecting to Floating island (fiction) per -R would be strongly preferable to deletion
