Universal Orlando Resort, often shortened to Universal Orlando, is a 541-acre (219 ha) theme park and entertainment resort complex located in Orlando, Florida. Following the opening of Universal Studios Florida in 1990, NBCUniversal moved forward with plans to expand from a single park into a large resort hoping to compete with Walt Disney World. In 1999, a second theme park called Islands of Adventure opened in addition to CityWalk, a shopping promenade and nightlife district that incorporates a variety of themed hotels, restaurants, and retail outlets. A third 30-acre (12 ha) water theme park, Volcano Bay, was added in 2017, and a fourth upcoming theme park, Epic Universe, is scheduled to open in 2025.

An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects.
