You dont say whether you have some status with any of the hotel programs you mention. We just finished a stay at Hilton Tokyo - it has a good location with easy access to subway and the rest of Tokyo, a good breakfast buffet, and we were treated very well there. I would also contunue to check prices, as they will fluctuate. We had a Tower suite, a separate bedroom and living room with large sectional and desk. It was a very large space. It does only have a single bathroom for the suite.
