The key difference between a 3- and 4-star hotel in Corona will be the standard of service and access to creature comforts. Three-star hotels are usually more budget-friendly and come with the services and conveniences you need to be comfy, such as WiFi, a gym and breakfast. You can look forward to a little more at a 4-star hotel — think upmarket interiors, premium toiletries and extras like on-site day spas.
