I booked this hotel because:
It was a Marriott
It was the cheapest
It was the closest to Haneda by cab
The room I selected had three beds, so made it easier for us when sleeping

Through more research, I ended up finding out it was a 3 minute walk from Shinagawa station so this was an added bonus. I pre purchased Suica cards for the family which made it easier for us to hop on/off the train. The train ride took approximately 25 minutes and was packed to the gills. Mostly everyone got off at Shinagawa as it is also an interchange station to other subway lines. I was thankful it was a cool evening and was a relief from the warm temperatures of the plane, airport and train.

As we walked up to the front doors of the hotel, a staff member came over to us and took our carry-on items (we checked our luggage all the way to CGK) and then escorted us to reception. The staff were all welcoming and the formalities were completed quickly. With keys in hand, we headed to our room. After freshening up, we headed back towards Shinagawa station for a quick dinner in the food court and just to walk around the area. Totally forgot to take pictures but by this time we were all beginning to get sleepy and got back to our room, showered and went to bed.
