During World War II, the Centre was closed to regular guests, but the staff became involved in reuniting refugees, many of whom had Guiding and Scouting connections. The Centre was also used for training military skiers and interning foreigners. The Swiss Guides were the only Guides who were able to use Our Chalet during the war, except for some French Guiding Commissioners who showed up in 1942. Many refugees came to Switzerland during the war and the staff tried to accommodate them in Our Chalet, but this was not allowed in most cases due to wartime regulations. However, the staff did help them with relief funds from the Guides and Scouts of Switzerland, Great Britain, and the United States. The Our Chalet staff found great joy in helping reunite families who had been divided by war. American Girl Scouts also donated substantial funds to Our Chalet in 1944, through the "U.S.A. Friendly Fund", to help with postwar recovery efforts.
