SHIRAHAMA KEY TERRACE HOTEL SEAMORE
forumWhat families say
Rakuten Travel rating 4.3 out of 5 (2,265 reviews). Guests recommend the hotel for families with young children and for larger group trips, and one guest traveling with a 3-year-old was pleased with how helpful the staff were and with the range of facilities, including the pool, onsen and playroom. Some also report that their children were delighted by the sashimi at the evening buffet. On the other hand, guests note that the buffet does not take reservations and gets crowded easily, so anyone hoping for a calm meal may want to consider a different plan.
