The key difference between a 3- and 4-star hotel in Bay will be the quality of service and access to creature comforts. Three-star hotels are generally more wallet-friendly and provide the conveniences and services required to be comfy, such as breakfast, WiFi and a gym. You can look forward to a bit more at a 4-star hotel — think upscale furnishings, deluxe bathroom products and extra touches like day spas.
