I've had "Butlers" at numerous properties but the only time I was really impressed was at the Armani Hotel in Dubai where you are given personal "Lifestyle Managers" who really take care of you and are available 24/7 for anything.

Our lifestyle manager accompanied us to the mall a couple of times, found me a good Dentist and made sure that the room was stocked with exactly what we liked.

The "Butler Service" offered at Shangri-La, St. Regis and numerous other brands is just a gimmick
