The main difference between a 3- and 4-star hotel in Bill will be the quality of service and access to creature comforts. Three-star hotels are usually more pocket-friendly and offer the services and conveniences you need for your comfort, such as WiFi, a gym and breakfast. You can expect a bit more at a 4-star hotel — think upscale décor, deluxe toiletries and extra touches like spa and wellness centres.
