If you want to pull out all the stops and make an impression, then hold your next conference at the Hôtel de Crillon. Among its five meeting rooms and eight historic salons, the Salon Marie-Antoinette is a listed Historical Monument, with Corinthian colonnades and a spacious terrace overlooking the Place de la Concorde. Rumor has it that the notorious French queen once took her music lessons in this room, and today it often serves as a venue for elegant cocktail receptions. While the hotel is awash in eighteenth-century style, its high-tech gadgetry belongs to the modern day. There is also a 24/7 business center, with office-away-from-office services to complement the organizational assistance you will receive from the personal project manager assigned to your event.
