forumWhat families say
Rakuten Travel rating 4.09 out of 5 (5,594 reviews). Guests praise the breakfast and dinner buffets for their variety, including eel and steak, and one family traveling with a one-year-old reported being able to move around the dining venue with their tray on a cart. Staff also drew praise for attentive service, such as suggesting rooms suited to families with children and providing a humidifier. On the other hand, guests note that the wait for elevators is long during busy periods, which can be hard on families with small children and on older travelers.
