BANGKOK/TOKYO -- Bruno Huber says he is the happiest hotel manager in Bangkok: He actually has guests in his 293-room luxury property. A former Hilton, its legendary garden was once famous for fertility shrines dotted with large, garish wooden phalluses. Today, the garden is every bit as manicured and regal as before, but guests maintain a safe distance from each other as they tramp anticlockwise around the grounds, taking their pre-booked 45-minute exercise breaks.
