I had stayed at Yokohama Bay Sheraton 13 stays , Sheraton Grande Tokyo Bay 5 stays and Westin Tokyo once in the last year and I am now in Yokohama Bay. All stays were for my business in Tokyo. As RichardInSF says, Sheraton Grande Tokyo Bay is isolated. Yes, it is true and this hotel is for Tokyo Disney Resort. But it is only 15 mins from Tokyo station on Keiyo-line, so it is no problem with my business. Yokohama Bay is only within 30 mins from Tokyo station on Sobu-Yokosuka line and also within 30 mins from Shinjuku on Shonan-Shinjuku line. Choose Yokohama Bay Sheraton This hotel is a very lovely hotel. Otherwise I never stay here so many times.
