In Nueva Guinea, a hotel must provide a certain amount of high-end amenities to be rated 5 stars. These can include on-site gyms, saunas and spas, gourmet restaurants, luxury toiletries, premium bedding and more. What also sets 5-star hotels apart is their outstanding service. You can look forward to things like in-room massages, concierge services and nightly turn-down services. Some may also offer special touches such as a welcome gift.
