The big difference between a 3- and 4-star hotel in Alto Parnaiba is the standard of service and availability of creature comforts. Three-star hotels are generally lower priced and provide the services and conveniences you need to be comfortable, such as breakfast, a gym and WiFi. You can count on a little more at a 4-star hotel — think upscale décor, deluxe toiletries and extras like day spas.
