The principal difference between a 3- and 4-star hotel in Outer Manchuria will be the level of service and availability of creature comforts. Three-star hotels are usually more affordable and provide the conveniences and services you need to be comfy, such as WiFi, breakfast and a gym. You can count on a little bit more at a 4-star hotel — think upmarket décor, deluxe bathroom products and perks like day spas.
