Question: What company owns at least two of the four casinos at the intersection of Tropicana Avenue and Las Vegas Boulevard?
Context: The Las Vegas Strip is a stretch of South Las Vegas Boulevard in Clark County, Nevada, known for its concentration of resort hotels and casinos.  The Strip is approximately 4.2 mi in length, located immediately south of the Las Vegas city limits in the unincorporated towns of Paradise and Winchester.  However, the Strip is often referred to as being in Las Vegas.  Most of the Strip has been designated an All-American Road, and is considered a scenic route at night. State Route 591 was a 0.242 mi state highway running east–west in the Las Vegas Valley along Spring Mountain Road.  The road parallels Spring Mountain from just east of Valley View Boulevard to just west of Rainbow Boulevard.  Spring Mountain Road has one terminus at Las Vegas Boulevard on the east and Hualapai Way on the west.  East of Las Vegas Boulevard, Spring Mountain becomes Sands Avenue, and again to Twain Avenue east of Koval Lane.

The Tropicana – Las Vegas Boulevard intersection on the Las Vegas Strip (Tropicana Avenue and Las Vegas Boulevard), is noteworthy for several reasons.  It was the first intersection in Las Vegas completely closed to street level pedestrian traffic and its four corners are home to four major resorts: Excalibur Hotel and Casino, Tropicana Las Vegas, New York-New York Hotel and Casino and MGM Grand Las Vegas—the latter has 5,044 rooms and was once the largest hotel in the world.  The resorts at the four corners have a total of 12,536 hotel rooms as of 2016.

The El Cortez, a hotel and casino, is a relatively small downtown Las Vegas gaming venue a block from the Fremont Street Experience and Las Vegas Boulevard.  The official marketing slogan has been "Where locals come to play" since the El Cortez has traditionally attracted Las Vegas residents weary of large casinos geared towards tourists.  Slots, table games, and a race and sports book occupy one floor of the main pavilion.  It is one of the oldest casino-hotel properties in Las Vegas having continuously operated at the same Fremont Street location since 1941.  Primarily Spanish Colonial Revival in style, it reflects a 1952 remodel when the facade was modernized.  On February 22, 2013, the structure was placed on the National Register of Historic Places.

In 1982, the El Rancho Hotel and Casino formerly known as the Thunderbird and later as the Silverbird opened across the street from the former site of the El Rancho Vegas, creating some confusion. Sloan is an unincorporated community with a population of 105 (as of the U.S. Census 2010) in Clark County, Nevada, situated 18 miles southwest of Las Vegas.  It is named for its limestone dolomite carnotite and was first settled in 1912 under the name Ehret, NV; named for the founders family name, but changed its name to Sloan on September 11, 1922.

Most of the residential areas are located on the main street, Sloan Road, and other smaller roads such as Arville Street, Hinston Street, and Roark Avenue.  It is adjacent to the Interstate 15 in Nevada.  To get here from Las Vegas, take Interstate 15 south and take exit 25 at Sloan.  On Las Vegas Boulevard, turn right for the residential areas and George W. Dunaway Army Reserve Center, while turn left and follow Las Vegas Boulevard for 0.1 mile to reach the road leading to Sloan Canyon National Conservation Area.  Following the power line road is treacherous.  A faster, safer, and brand new paved road through the Henderson neighborhood of Anthem takes you to the Sloan Canyon visitors center and trailhead to the Petroglyphs.
