The main difference between a 3- and 4-star hotel in Palagruza Island is the standard of service and access to creature comforts. Three-star hotels are usually more economical and offer the services and amenities you need to be comfortable, such as breakfast, a gym and WiFi. You can look forward to a bit more at a 4-star hotel — think upscale furnishings, luxury bathroom products and extras like on-site spas.
