I'm considering staying at either the St. Regis or the Peninsula Palace in mid April. (I've already read the other threads so I know the ins/outs of each one). Does anyone know of a discount site or better place to get good rates other than the hotel websites or Orbitz/Expedia/Travelocity? They area all showing the same rates (Peninsula: $195 Deluxe, $240 Grand Club, $337 Duplex Suite; St. Regis: $265 Deluxe). I'm an Amex Platinum member and their rates weren't any different but do have the welcome ammenity and upgrade when available. Thanks in advance!
