The Rooms
Sheraton Grande Tokyo Bay has a bewildering array of rooms, in all manner of configurations.
Suffice to say that only the OCEAN DREAM rooms and the CLUB rooms are newly renovated (as of Dec 2015). I was given a choice of either and chose the Club room, preferring the darker colours. Take the Ocean Dream if you prefer something brighter and more child-friendly.
I was assigned a corner room, spacious enough for a family of 6 if you squeeze. We were a party of four and each had his/her bed. The alcove that houses two super singles was very cramped but usable. You can see it in one of the pictures below.
I was very happy with the renovations - everything was brought up to date, and there were many nice nautical touches. I'll let the pictures do the talking...
They always remember birthdays, and you get a towel "cake", a card, and assorted yummies
