Business Notes HOSTELRIES

Aging stars and starlets of the world, take notice. For those planning a face- lift or tummy tuck, there is a place to hide away in dignity while the sutures and bruises are healing. Le Petit Ermitage in Beverly Hills is claiming an unusual specialty: luxury postoperative care for plastic-surgery patients. The hotel gives patients 24-hour nursing, skilled assistance with makeup, a limousine (with tinted-glass windows, naturally) for trips to the doctor, and gourmet food. Most important is the obsessive privacy -- all calls and visitors are screened. The rate: from $275 a night for one to as much as $550 for couples who check in for simultaneous make-overs.
