The key difference between a 3- and 4-star hotel in Lehigh will be the standard of service and availability of creature comforts. Three-star hotels are typically more budget-friendly and provide the services and conveniences required to be comfy, such as WiFi, breakfast and a gym. You can look forward to a little bit more at a 4-star hotel — think upmarket furnishings, deluxe toiletries and extras like spa centres.
