Veuve Clicquot underground chalk cellars (24 km of UNESCO chalk mines below Reims) — the bride's signature pour, the brand history walk, the multi-cuvée tasting. Day two: Krug + Pommery cellars (Pommery's chalk pit museum + cuvée tasting is the bride's pick), Reims Cathedral day. Day three: a final hosted tasting at Ruinart (the world's first Champagne house, 1729). Sleep at La Caserne Chanzy (boutique 4-star in restored barracks). Paris (CDG) + 45-min TGV.
Five quick questions, then we build the full itinerary — lodging, daily schedule, dining, bars, the group-chat message — and drop you into a Trip Room you can share with the bridesmaids.
