Dragon Party 2000 was held in Saint-Caprais-de-Bordeaux, France.

Date and location confirmed by this page from ojuice.net on the Wayback Machine and this page on the Hugi website. The party used to have a website at http://www.dragon-party.fr.st but unfortunately that is long gone from the web, and none of the captures on Wayback gleam much useful information since none of the subpages are present in the few that actually don't just give errors.
