The principal difference between a 3- and 4-star hotel in Arctic National Wildlife Refuge is the quality of service and access to creature comforts. 3-star hotels are generally more budget-friendly and come with the services and conveniences required to be comfy, such as breakfast, WiFi and a gym. You can look forward to a little more at a 4-star hotel — think upmarket interiors, luxury bathroom products and extra touches like day spas.
