The biggest difference between a 3- and 4-star hotel in Great Allegheny Passage is the quality of service and availability of creature comforts. Three-star hotels are generally more economical and include the amenities and services you need to ensure your comfort, such as breakfast, a gym and WiFi. You can look forward to a bit more at a 4-star hotel — think upscale furnishings, deluxe toiletries and extra touches like on-site day spas.
