The big difference between a 3- and 4-star hotel in Nueva Guinea is the level of service and availability of creature comforts. Three-star hotels are typically more economical and come with the services and conveniences you need to be comfortable, such as breakfast, a gym and WiFi. You can count on a little bit more at a 4-star hotel — think upscale furnishings, premium toiletries and extras like on-site spa centers.
