user: Give me a brief history of the construction of Walt Disney World

assistant: Walt Disney World was designed as a theme park to supplement Disneyland.  It was conceived by Walt Disney in the 1960s and was known as the "The Florida Project".  Walt Disney originally envisioned including a planned community known as the "Experimental Prototype Community of Tomorrow" (EPCOT) which would be a planned community that would test city-living innovations.  As planning progressed, plans for EPCOT evolved to become just a theme park in the complex.  Walt Disney died in 1966 during planning and the company was torn whether to move forward with the project.  Walt Disney's brother, Roy Disney, came out of retirement to see the project successfully completed.  There are four theme parks in the complex.  The Magic Kingdom opened in 1971, followed by Epcot in 1982, Disney's Hollywood Studios in 1989, and Disney's Animal Kingdom in 1998.  Roy Disney insisted the name be changed to Walt Disney World from the original name of just Disney World to remind people that it was Walt's dream.

user: What are the key elements of a sauna?

assistant: Saunas are a room with a heat source that will hold room temperature between 150 and 220 degrees Fahrenheit. The heat source is electric or wood fire. Typically saunas have an 8’ ceiling, and the size of the room is optimized for the number of people that are expected to use it concurrently. Saunas also need benches. The optimal bench depth is 24” to allow users to lay down comfortably. Bench and wall paneling is typically western red cedar, although other wood types that can withstand high swings in temperature are suitable as well. Proper wall, ceiling, and even floor insulation is critical, and given there will be water vapor in the room, there needs to be a vapor barrier between the wall panels and insulation. A floor drain is also highly encouraged.
