Reading this with interest as I have currently got the Kimpton booked for one night in March. I was looking at the Regent but then for the price of the lowest room at Regent, you can get a suite at the kimpton.
We have a 2 year old and my wife is much more sensible than me. She says we should just keep the booking at the Kimpton (49,000 points) and hope our diamond gets us a slight upgrade.
