Traveling from Tokyo to Osaka using the Hokuriku Arch Pass: What are the recommended hot spring inns in Kurobe Unazuki Onsen?

北陸アーチパスを使って1週間かけて東京から大阪を旅します。せっかくなので温泉に入ろう！と黒部の宇奈月温泉で1泊したいのですが、朝食、夕食付きで温泉に入れるホテルを教えてください。露天風呂か外の景色を眺められるお風呂に入りたい。4人旅ですが、2人ずつの二部屋になってもよいです。

Please tell me about a lodging in Unazuki Onsen that has a family bath that is recommended for traveling with children.

I'd like to go to Unazuki Onsen with family of four during spring break. I have two small elementary school-aged children, so I'd like to stay two nights at an inn that has a family bath or a private bath. Please tell me about an hot spring with breakfast and dinner included. I'd like an inn with a parking lot because I'll be going by car.
