Down and Out in the Magic Kingdom by Cory Doctorow

Emotional Maturity Is Physical Maturity: No one so much as bats an eyelash at the Mayfly–December Romance anymore, since physically nearly everyone has a twenty-something body.

Drugs Are Good: Since addiction is easily cured and health consequences don't mean much to immortals, there are casual in-passing references to the main character's girlfriend smoking crack.

Disney Theme Parks: Primarily set in them, particularly a future Magic Kingdom.

Crapsaccharine World: Yes, everyone's effectively immortal and money has disappeared, but half the characters smoke crack to overcome how boring the world is, while a bunch of others have put their minds in storage until something interesting happens.

Body Backup Drive: Everybody has access to cloned bodies that they can download their memories into when they die.

The story chronicles one of a group of adhocrats running The Haunted Mansion at Disney World, trying to solve his own murder after he is killed prior to the hostile takeover of said attraction by another ad-hoc committee. Bursting with cutting-edge speculation and human insight, Cory Doctorow's Down and Out in the Magic Kingdom is a coming-of-age romantic comedy and a kick-butt cybernetic tour de force.A novel by Cory Doctorow set in the future of the Bitchun Society, which has abolished conventional money (replaced by Whuffie, a complex reputation-based system), scarcity (cheap renewable energy and nano-assemblers), death ( brain uploads and subsequent downloads to fast-grown clones), and government (entirely ad-hoc structures). (It's only his fourth death and revival, after all.) Now it's war: war for the soul of the Magic Kingdom, a war of ever-shifting reputations, technical wizardry, and entirely unpredictable outcomes. Worse: it appears this new group has had Jules killed. For Jules, this is an attack on the artistic purity of Disney World itself. A new group has taken over the Hall of the Presidents and is replacing its venerable audioanimatronics with new, immersive direct-to-brain interfaces that give guests the illusion of being Washington, Lincoln, and all the others. Now, though, it seems the 'ad hocs' are under attack. Now in the care of a network of volunteer 'ad-hocs' who keep the classic attractions running as they always have, enhanced with only the smallest high-tech touches. Disney World! The greatest artistic achievement of the long-ago twentieth century. He's lived long enough to see the cure for death and the end of scarcity, to learn ten languages and compose three symphonies.and to realize his boyhood dream of taking up residence in Disney World. Cory Doctorow's debut cyberpunk science fiction that explores the scarcity of morality in a world that has conquered death and material insufficiency―now repackaged with a new cover! Jules is a young man barely a century old.
