The mechanism is single and centralized: everything runs through the official site lvmh.com, which publishes a "Catalogue of Experiences" listing the 69 sites, filterable by region (Africa, America, Asia-Pacific, Europe). Entry is booked free of charge by time slot, subject to availability, with no code and no referral. There is no paid ticket, no purchasable VIP access, and no official resale: the event is financed by LVMH and its Maisons. Each venue, however, sets its own age and access conditions. In Paris, the 2026 edition notably opens the private mansions of Place Vendôme. Chaumet, at No. 12, offers the "Diadèmes de Rêve" visit, free with booking, accessible to visitors with reduced mobility, from age 6. Repossi opens its historic boutique at 6 Place Vendôme, its headquarters since 1986, which marks its 40th anniversary in 2026 (from age 8, accompanied). Bvlgari and Fred take part on the same square and on Rue de la Paix. For any question, the institutional channel is lesjourneesparticulieres@lvmh.com, tel. +33 (0)1 44 13 22 22 (LVMH, 22 avenue Montaigne).
