The most obvious difference between a 3- and 4-star hotel in Lake Louise is the quality of service and availability of creature comforts. Three-star hotels are usually more wallet-friendly and provide the services and amenities required to be comfy, such as WiFi, a gym and breakfast. You can count on a bit more at a 4-star hotel — think upscale furnishings, luxury toiletries and perks like on-site spa centers.
