Question: How many acres does Luna Park cover?
Context: The Big Dipper was a wooden roller coaster operating at Luna Park Sydney from 1935 until 1979.  It was demolished in 1981.  First constructed in 1930 to an American design, the wooden Big Dipper roller coaster was a mainstay of Luna Park Glenelg during its four years of operation.  The ride was dismantled and shipped to Sydney when the Glenelg park went into voluntary liquidation in 1934, and became the biggest attraction of the newly opened Luna Park Milsons Point (which was later renamed Luna Park Sydney). Luna Park was an amusement park in Seattle, Washington that operated from 1907 until 1913.  Designed by famed carousel carver Charles I. D. Looff, who carved and installed Coney Island’s very first carousel, Luna Park took its name from Coney Island’s Luna Park.  On July 4, 1908, Luna Park became the site of Seattle’s first manned flight. Osaka's Luna Park ("Runa pāku", also known as Shinsekai Luna Park) was Japan's second amusement park of the same name, replacing the destroyed Luna Park in Tokyo.  In operation from 1912 to 1923, the 132,000 square meter park in the Shinsekai section of Osaka featured a unique entrance: an aerial tramway from the original Tsutenkaku Tower. Luna Park Sydney (originally Luna Park Milsons Point, also known as Sydney's Luna Park) is an amusement park located in Sydney, New South Wales, Australia.  Luna Park is located at Milsons Point, on the northern shore of Sydney Harbour. Luna Park is the name of an amusement park in the neighborhood of Coney Island, Brooklyn in New York City that opened on May 29, 2010 at the former site of Astroland, an amusement park that had been in operation for 46 years.  It was named after the original 1903 Luna Park which existed until 1944 on a site just north of the current park's 1000 Surf Avenue location. Luna Park was one of several names for an amusement park that existed in Rexford, New York, near Schenectady, from 1901 to 1933.  In addition to Luna Park (the name given by developer/entrepreneur Frederick Ingersoll when he added rides and assumed control of Rexford Park in 1906), it was also known as Dolle's Park (named after Fred Dolle, who bought the park from Ingersoll in 1912), Colonnade Park, Palisades Park, and (again) Rexford Park (in 1916) before the rides were dismantled in 1933.  Constructed around the Grand View Hotel (built and opened by Jacob Rupert in 1901), the park was similar to Ingersoll's other Luna Parks in which it was a trolley park with roller coasters, picnic pavilions, carousels, a fun house, a roller rink, a concert shell, a dance hall, a midway, a Whip, and a shoot-the-chutes ride which presented itself at the park entrance adjacent to a station of the Van Vranken electric trolley line.  Roughly seven decades before the Skycoaster rides that now dot various United States amusement parks, Luna/Rexford Park featured an aerial swing ride. The Cairo Luna Park was a trolley park in Heliopolis, Egypt.  Open from 1911 to the beginning of 1915, the Cairo Luna Park was the first Western-style amusement park in Africa and the first in the Middle East.  On 19 January 1915, buildings and grounds were converted into an auxiliary hospital at Luna Park for World War I; the hospital was closed on 10 July 1916. Luna Park (also known as Luna Park Arlington, Luna Park Washington, and Luna Park Washington D.C.) was an amusement park in Arlington, Virginia, USA, from 1906 to 1915.  A trolley park that was constructed (for $350,000) and owned by Frederick Ingersoll, the park occupied 34 acre near the intersection of South Glebe Road and Jefferson Davis Highway (U. S. Route 1) and featured a figure eight roller coaster, a shoot-the-chutes ride, a ballroom, circus arena, restaurants, and picnicking facilities for 3000 people.  Exhibits were housed in buildings displaying different architecture styles (Japanese, Moorish, Gothic). Astroland is a 3.1 acre abandoned amusement park in Coney Island, Brooklyn, New York City that first opened in 1962.  It was located at 1000 Surf Avenue (at the corner of West 10th Street) on the boardwalk.  It ceased operations on September 7, 2008. In operation in 1910 and 1911, Tokyo's Luna Park ("Runa pāku", also known as Asakusa Luna Park) was the first park of that name to be open in Japan.  Owned and constructed by the Japanese motion picture company Yoshizawa Shōten (headed by Ken'ichi Kawaura) in the Tokyo suburb Asakusa, the park was designed to mimic the original Luna Park that was built in Brooklyn, New York in 1903.
