Question: The Fountainebleau Las Vegas was intended to be a sister property to what hotel in Miami Beach that was opened in 1954, and was designed by Morris Lapidus?
Context: The Venetian Islands are a chain of artificial islands in Biscayne Bay in the cities of Miami and Miami Beach, Florida.  The islands are, from west to east: Biscayne Island (Miami), San Marco Island (Miami), San Marino Island (Miami Beach), Di Lido Island (Miami Beach), Rivo Alto Island (Miami Beach), and Belle Isle (Miami Beach).  Flagler Monument Island remains an uninhabited picnic island, originally built in 1920 as a memorial to railroad pioneer Henry Flagler.  The islands are connected by bridges from the Miami mainland to Miami Beach. Morris Lapidus (November 25, 1902 – January 18, 2001) was an architect, primarily known for his Neo-baroque "Miami Modern" hotels constructed in the 1950s and 60s, which have since come to define that era's resort-hotel style — synonymous with Miami and Miami Beach. The Bass Museum of Art is a contemporary art museum located in Miami Beach, Florida in the United States.  The Bass is currently closed for renovations and opens to the public in 2017.  During renovations, The Bass Projects has operated a temporary exhibition space at the Miami Beach Regional Library (227 22nd Street).  The Bass Museum of Art was founded in 1964 through the donation of a private collection by John and Johanna Bass to the City of Miami Beach.  The museum opened in what was formerly the Miami Beach Public Library and Art Center, a 1930s Art Deco building designed by Russell Pancoast, grandson of Miami Beach pioneer John Collins.  The building was placed on the National Register in 1978. The Capitol Skyline Hotel is a hotel located near the United States Capitol in Capitol Hill, Washington, D.C. Designed by Morris Lapidus, the hotel opened in November 1962 as the Skyline Inn, and was once part of the Best Western chain. BayLink is a long proposed transit connection between Miami and Miami Beach, Florida.  Proposals have ranged from streetcar, light rail, monorail, Metromover, or Metrorail extension that would connect Downtown Miami to South Beach via the MacArthur Causeway, with the light rail or streetcar options potentially having loops at both ends.  Originally proposed as an elevated light rail line such as a monorail, Miami Beach city officials opposed this in favor of something less intrusive, such as a streetcar.  Historically, Miami Beach has also cited concerns of unwanted downtown residents as a detriment to the South Beach image.  Additionally, the unused parts of the bases of the MacArthur Causeway bridge pilings that were to be used to support the line have been used for the widening of the causeway for the construction of the Port Miami Tunnel, complicating a fully separated right of way.  Officials still thought it was feasible as a light rail streetcar, and in 2014 were considering the possibility of a public-private partnership to help fund it.  In 2015, the cities of Miami and Miami Beach decided to break the estimated $532 million system into three pieces; two compatible light rail loops in Downtown Miami and South Beach to later be connected via MacArthur Causeway.  This was motivated by the lengthy federal studies required for a larger project.  French transport vehicle manufacturer Alstom gave an unsolicited proposal to build the Miami Beach portion of the system for US$148 million as a wireless streetcar system from 5th Street to Dade Boulevard via Washington Avenue.  Alstom predicts over 20,000 riders a day just on the eight to ten stations that would be on the Miami Beach segment. The Fontainebleau Miami Beach (also known as Fontainebleau Hotel) is one of the most historically and architecturally significant hotels in Miami Beach, Florida.  Opened in 1954 and designed by Morris Lapidus, it was arguably the most luxurious hotel in Miami Beach, and is thought to be the most significant building of Lapidus's career.  In 2007, the Fontainebleau Hotel was ranked ninety-third in the American Institute of Architects list of "America's Favorite Architecture".  On April 18, 2012, the AIA's Florida Chapter ranked the Fontainebleau first on its list of "Florida Architecture: 100 Years.  100 Places". Belle Isle is a neighborhood of South Beach in the city of Miami Beach on a barrier island in Biscayne Bay, Florida, United States.  It is the easternmost of the Venetian Islands, a chain of artificial islands in Biscayne Bay in the cities of Miami and Miami Beach.  It is home to apartment buildings, a portion of the Venetian Causeway, a city of Miami Beach park, and a hotel.  It is between Rivo Alto Island and the main barrier island of Miami Beach. The Carillion Hotel & Spa, and the Carillion Residences, formerly known as Canyon Ranch Miami Beach, is a complex of three high rise luxury condominiums in North Beach, Miami Beach, Florida, United States.  It is located on the beachfront on the east side of Collins Avenue between 68th and 69th Streets.  The Carillon Hotel & Spa complex includes The Carillon Hotel & Spa North Tower, the 20 floor The Carillon Hotel & Spa South Tower, The Carillon Hotel building located between The Carillon Hotel & Spa Towers on Collins Avenue, as well as the proposed Golden Sands Canyon Ranch proposed to be built north of The Carillon Hotel & Spa North Tower.  The old Golden Sands Hotel and Lounge is being demolished to make way for the new Golden Sands building.  The 15-story Carillion Hotel building was built in 1955 but was vacant for 15 years until it was renovated in 2007 and became part of the Canyon Ranch complex.  The 22 floor The Carillon Hotel & Spa South Tower is 257 feet (78 meters) tall and was completed in 2008.  The tallest building, the north tower of The Carillon Hotel & Spa is 37 floors and 121 meters (~400 feet) tall, was completed in 2008 and is one of the tallest buildings in Miami Beach.  The Carillon Hotel & Spa North Tower looks like two separate, connected towers, but both are the North Tower building.
