Full disclosure, I haven't read the trip reports. All the hotels mentioned are high end and I'm sure will impress. We stayed at the Hyatt Regency on Points and Cash as a Plat a year and a half ago, received an upgrade to a larger room. We thought it was a pretty good deal and didn't have enough points for the PH.
Tokyo is one of the top food cities in the world, unless you keep kosher. I wouldn't let the hotel's willingness to order in kosher breakfast be a deciding factor. I would recommend packing your own for breakfast and suplemmenting with fresh fruit. It can be expensive, but tends to be really tasty.
