The most obvious difference between a 3- and 4-star hotel in Dyer will be the quality of service and availability of creature comforts. Three-star hotels are generally more economical and include the services and amenities required to be comfortable, such as WiFi, breakfast and a gym. You can expect a little bit more at a 4-star hotel — think upscale furnishings, luxury bathroom products and perks like on-site day spas.
