The biggest difference between a 3- and 4-star hotel in Niihau is the standard of service and availability of creature comforts. Three-star hotels are typically more pocket-friendly and offer the amenities and services you need to be comfortable, such as WiFi, a gym and breakfast. You can look forward to a bit more at a 4-star hotel — think upscale décor, premium bathroom products and extra touches like on-site spas.
