Overall, the hotel is very nice and clean. But one small drawback is the lack of an individual toilet.

夜11時までと、朝7時から露天風呂に入れます。 朝食レストランは和食中心バイキングですが美味しく、海が見えるのが良い。 千畳敷まで近いので散歩に良さそうです。 今回はアドベンチャーワールド目的で宿泊しましたが、すぐ近くのバス停から行けます。 白浜駅から、夜タクシー利用で三千円程度でした。 この内容と料金は満足できました。
クロワッサンや、食パン、ドリンクバーもありました。

三日間滞在しましたが、近くに飲食店、コンビニがなく、レストランも夕食予約者のみ対応で夕食には苦労しました。車で来る宿ですね。不便さを承知の上で宿泊すればコスパはいいと思います。
