Hotel Sacher Wien — the 1876 imperial-era hotel, the original Sachertorte recipe vault, the bride's apex Vienna base. Day-one Belvedere Palace for the Klimt collection (The Kiss in person), Vienna Staatsoper standing-room ($5-10) for any night's opera. Day two: Hofburg Spanish Riding School morning training session ($15-20), Café Central afternoon (the marble pillars + the apple strudel). Day three: Heuriger wine tavern in Grinzing for the bride's casual closing dinner. Vienna (VIE) is direct.
