Orlando is the largest inland metropolis in Florida, best known as the home of the massive Walt Disney World and Universal Orlando theme park suites, which attract over 68 million annual visitors throughout their operating seasons. Visitors can stay at luxury hotels on the resorts' complexes or explore the urban center of the "City Beautiful," which is home to over 148 lush public parks and green areas. Just outside of city limits, a number of wildlife preserves protect the sensitive marsh and wetland environments of the central Florida region. The Disney Springs and Universal CityWalk shopping and entertainment districts also showcase nightly fireworks shows and a plethora of name-brand stores, delicious restaurants, and hip nightlife districts.
