forumWhat families say
Rakuten Travel rating 4.45 out of 5 (488 reviews). Several guests report that their children had a great time playing in the plaza beside the lobby and in the well-equipped playroom. Some reviews also praise the rooms with a jacuzzi for children who cannot yet use the communal bath on their own. On the other hand, guests point out that on busy evenings the communal bath gets crowded with day-use visitors, to the point that washing stations are hard to come by.

Overview
Hotel Seaside Shimabara is a hot-spring resort hotel on the Ariake Sea in Shimabara, Nagasaki. Every room apart from the single rooms has an ocean view, and two kinds of bath water - Shimabara onsen and highly concentrated carbonated spring water - can be enjoyed in the communal bath and the open-air bath. There is also the playroom Kidpia, free for staying guests, and Korassanne Plaza, a lawn plaza with play equipment. Children can co-sleep, and charges apply from age 3. Children's menus and amenities are available as well, making this an easy hotel to stay at with young children.
Rooms
Apart from the single rooms, every room has an ocean view over the Ariake Sea. The Japanese-Western rooms on the 3rd and 4th floors of the new wing add a tatami area to the bedroom and use cushioned flooring, so families with children can relax with peace of mind. The ocean-view Japanese-Western room is 36.1 sq m for 1 to 5 guests, combining a 4.5-tatami Japanese-style area with twin beds 120 cm wide. The twin room (26.5 sq m, for 1 to 2 guests) also has beds 120 cm wide and comes with a terrace. The 6th floor of the new wing has rooms with an open-air bath and a jacuzzi (29.7 sq m, for 1 to 2 guests), and there is also a spacious suite of 56.3 sq m for 1 to 4 guests, so you can pick a room type to match the size of your family. Guest rooms are equipped with a humidifier, while a microwave and a mini kitchen are available in some rooms only and require advance reservation. The bathtubs in the guest rooms are not fed by the onsen.
Dining
Breakfast is served buffet-style at the restaurant Alba. It costs 1,500 yen for adults and 750 yen for children from age 3 through elementary school. For children there are Western-style and Japanese-style kids' meals, plus a kids' meal designed for elementary school children. Older elementary school children can have a set built around Hamburg steak and fried prawns, while younger elementary school children and children who have not yet started elementary school can have a set with small rice balls and udon, so you can choose by age.
Baths and Onsen
The Tojidokoro on the 1st floor of the main building and the panoramic communal bath on the 6th floor of the new wing both offer two kinds of water: the gentle Shimabara onsen and highly concentrated carbonated spring water, which is expected to help with recovery from fatigue. There are open, airy open-air baths and indoor baths, along with a sauna. Since the bathtubs in the guest rooms are not fed by the onsen, you need to go to the Tojidokoro or the panoramic bath to soak in the onsen.
Family-Friendly Features
Every room in the building is barrier-free, with no steps from the entrance to the guest rooms, so it is easy to get around with a stroller. Children can co-sleep, and charges apply from age 3. Children's amenities such as yukata, toothbrushes and body towels are provided during the stay. The playroom Kidpia, which staying guests can use free of charge, has three areas - a picture-book corner, a movie-viewing corner and a play corner - and is open from 7 a.m. to 10 p.m., making rainy days easy to fill. Outdoors, Korassanne Plaza is a lawn plaza covered in green all year round, with play equipment where children can play safely. Meals accommodating allergies can also be arranged.
