Having never stayed at a Peninsula hotel or even walked through one, not sure if I'm qualified to even comment. But if the location is similar as Doris makes it sounds, you probably couldn't go wrong picking either one. I LOVED our suite in the Regent - I was so sad that we really only got to spend a few hours and a night's sleep in it! I've got pics of the interior of our suite on my PANDA pictures if you haven't seen them.
