The most obvious difference between a 3- and 4-star hotel in Rio Grande will be the quality of service and access to creature comforts. Three-star hotels are generally more pocket-friendly and come with the amenities and services you need for your comfort, such as breakfast, a gym and WiFi. You can look forward to a little more at a 4-star hotel — think upmarket furnishings, deluxe toiletries and extra touches like day spas.
