I've heard of signature spa experiences or hiring your own chef to cook at your vacation home but a luxury bath menu? Imagine soaking in a decadent bath at the St. Regis hotel while enjoying La Maison du Chocolate truffles, Krug Grand Cuvee champagne, perhaps some Caspian Osetra caviar and one of the most relaxing moments money can buy (for about $1,650). Choose from four signature baths while in residence at these grand hotels -- and don't worry about the hour, it is available around the clock.
