Although the weather wasn't great when we boarded, we still saw different views of Tokyo Bay at night. I believe it would be even more beautiful with better weather. The staff were very warm and friendly. Drinks were also free to sample different beverages (both alcoholic and non-alcoholic). It was Halloween, and both the staff and the ship had festive decorations and activities. We had a wonderful evening.
