Eau Spa by Cornelia at the Ritz-Carlton, Palm Beach, Florida
What: A seemingly endless 42,000-square-foot fantasyland, with 19 treatment rooms, an oversized whirlpool, steam and sauna rooms, and a fanciful garden.
The look: Philippe Starck litelamp shades stenciled with neo-Victorian chandeliers, vintage novels, and Alice in Wonderland-style accents like an oversized chess set.
Who goes: Lilly Pulitzer-clad matrons with taut foreheads and perfect blow-outs, bronzed young things waiting for silver-haired stallions.
The treatment: Cult New York aesthetician Cornelia Zicu offers luxe, customized, hour-long facials; add the papaya-pumpkin enzyme booster, which gently tingles as it sloughs.
P.S.: Mix your own potion from aromatic herbs, salts, and oils at the scrub and polish bar (massages, $160-$295).
