forumWhat families say

Rakuten Travel rating 4.31 out of 5 (1,358 reviews). Guests praise the wide variety at both the dinner and breakfast buffets - fresh seafood, steak and crab - and families say their children were able to go back for seconds again and again. The exterior is older, but the interior is kept clean, and guests also praise the sea views from the rooms and the communal bath. On the other hand, some say the breakfast buffet gets crowded and that short chopsticks for children were not available.
