For a special treat it HAS to be the Penninsula...forget those American chains...ICH

Ok for a conference I'm sure.
The Penn is in a league of its own...an amazing hotel...the most incredible rooms and impeccable service. Book an Island view room and order a Rolls to collect you both off your flight...not as ostentatious as it might sound...just their town car...wonderfully elegant and indulgent. Afternoon tea is a must, and as a hotel guest no queueing...
I'm sure your wife loves you dearly but after a stay at the Penninsula she'll love you even more!!!
Enjoy the trip....
