It's great value for money; one ticket allows you to hop on and off at any time, especially convenient for Odaiba Station. Note that only the online QR code can be used!
The service and safety were both excellent. A pleasant surprise was that a guided tour was provided on the boat, offering views of the scenery along the way. The guide was also very humorous and charming. It was a pity the cherry blossoms weren't in full bloom yet, but I definitely plan to bring my family again next time ❤️
Since we visited on a weekday, we were able to try out many different jobs. The staff were all very nice, and my child was very happy after playing all day! As mentioned in other reviews, when we arrived around 8:30 a.m., there were already many people lining up.
Breakfast was delicious. The staff was friendly. It's great for traveling with babies. It's also great that it's connected to a shopping mall. The rooms were very dry. There's no room service.
