Disclave
From Wikipedia, the free encyclopedia
Disclave was a science fiction convention run by by the Washington Science Fiction Association (WSFA) in or near Washington D.C. in the springtime of nearly every year from 1950 through 1997.
At first it was intermittent and small, with an attendance as low as 22 people (in 1953). Starting in 1965, it happened every year. Starting in 1971, it was always on Memorial Day weekend, and always lasted three days. The highest attendance was 1485 (in 1979).
At the 1997 Disclave, a fire sprinkler broke, flooding much of the hotel. The 1998 Disclave (scheduled for a different hotel, on a different weekend) was cancelled six weeks before the convention by the hotel. No hotel could be found to hold a 1999 or 2000 Disclave.
In 2001, WSFA started hosting a new convention, Capclave, each autumn.

The Wardman Park became the Sheraton Park, also the site of Discon II, the 1974 Worldcon. Disclave was held there in 1950, and from 1972 through 1979.
Disclave was in the same hotel in New Carrollton from 1984 through 1991 and again in 1997. This hotel was called the New Carrollton Sheraton in 1984, The Sheraton Inn in 1985, The Sheraton Washington Northeast in 1986 and 1987, the Howard Johnson New Carrollton in 1988 and 1989, the Sheraton Greenbelt in 1990 and 1991, and the Ramada Inn Conference and Exhibition Center in 1997. As of 2006, its name is New Carrollton Hotel. The hotel will be converted to a Four Points by Sheraton in 2007.
