Carnival Cruises are the famous "fun ships". They are affordably priced and often attract families. Large facilities for kids programs keep the young ones happy while parents enjoy themselves too.
Onboard activities include WaterWorks with water slides, Serenity adults-only retreats, spa, fitness center, casino, live music, and bars.
The Carnival Miracle ship operates out of San Diego. It has had extensive renovations in recent years.
