The main difference between a 3- and 4-star hotel in Gettysburg is the level of service and availability of creature comforts. Three-star hotels are usually lower priced and come with the amenities and services you need for your comfort, such as WiFi, a gym and breakfast. You can count on a bit more at a 4-star hotel — think upscale décor, deluxe bathroom products and perks like spa and wellness centers.
