The key difference between a 3- and 4-star hotel in Main Brook is the level of service and availability of creature comforts. Three-star hotels are generally more affordable and provide the services and conveniences you need to be comfortable, such as a gym, WiFi and breakfast. You can look forward to a little bit more at a 4-star hotel — think upmarket furnishings, luxury toiletries and perks like on-site spa centers.
