The key difference between a 3- and 4-star hotel in Old Harbor will be the quality of service and access to creature comforts. Three-star hotels are usually more affordable and come with the services and conveniences required to be comfy, such as breakfast, WiFi and a gym. You can expect a little bit more at a 4-star hotel — think upscale furnishings, premium bathroom products and extra touches like on-site day spas.
