THE TAB: US$6,730 per person for six nights

And that rate doesn't cover spa treatments (up to US$1,625 for a week's worth). It does buy a full medical checkup, consultations, and nourishing meals. The expertise is deep (about 60 consulting doctors); the experience, coddling. Think European grand hotel meets sanatorium, with sparkling Alpine air and glorious Lake Geneva views. The new spa's forte is Beautymed, a regimen that can include electrified facials and plant-powered products. The dramatic results (for me, at least) justify the cost. — A.A.
