I assume you mean the recently opened Hard Rock Park, the world's first theme park devoted entirely to rock 'n' roll. And while we're not advocating the hard-living rocker lifestyle for a nine-year-old, this park is definitely family-friendly and suitable for younger kids. Instead of offering separate children-only areas like some other theme parks, Hard Rock has created six genre-specific zones (eg. British Invasion, Cool Country, Born in the USA) where there are rides, attractions, and amenities suitable for all ages. Check it out and let us know what you think!
