Nice resort with waterpark and onsen, very good restaurant. There is not much around the resort and it's quite far away from Da Nang center. The villa we've stayed in would need a bit of touch up here and there (dirty walls/ceiling, cracked sink), but had comfy beds and japanese toilet. Main hotel building looked good, food both at the main restaurant and at the waterpark was very good. Waterpark was great for kids, onsen was really good. Overall very nice resort.
Fun place for families with kids that love the water! The room at the Hinode Villa were very comfortable and provides closer access to the outdoor water park and the beach. There's also on-demand buggy service to ferry you around if you don't feel like walking.
A couple of suggestions: add more vegan food options across the on-premise restaurants, and some outdoor space could use a good maintenance (e.g. walkway in the Hinode Villa area).
