If you choose to spend your vacation at a 4-star hotel in Rock River, you'll usually find loads of conveniences to ensure you're relaxed, such as a pool, gym and restaurant. You can enjoy high-quality service and upmarket surroundings. Pick a 5-star hotel and you'll have access to a few extra bells and whistles — think on-site spas, 24-hour front desk and indulgent turndown services. You'll most likely get extra amenities and first-rate services at a 5-star getaway, though both are great options for luxury travelers.
