Woodbury Common Premium Outlets is an outlet center located in Central Valley, New York. The center is owned by Premium Outlets, a subsidiary of Simon Property Group, and takes its name from the town in which it is located. Opened in late 1985, expanded in 1993, and again in 1998, the center now has 220 stores occupying more than 800,000 square feet (72,000 m²) and is one of the largest contiguous outlet centers in the world. Due to its size, different areas are color-coded to help visitors orient themselves, and on weekends, trolleys are available to transport shoppers from the parking lots and around the center. Due to its proximity to New York City, Woodbury Common is a major attraction for foreign tourists visiting the region. Japanese tourists have been overtaken by Chinese tourists as the most frequent foreign visitors. Tour buses and shuttles make daily trips from New York City, the center employs a staff of interpreters, and currency exchange and foreign shipping services are available on site. Guests are greeted in several languages other than English including Japanese, Spanish, French and Portuguese.
