The Merry Christmas One and All residency runs across select dates from Nov 28 through Dec 13, 2025, a tightly staged holiday run that folds classic seasonal standards and signature Mariah moments into a single, elegant program. Expect generous arrangements of the season’s favourites, theatrical visual moments, and carefully paced setlists that trade in both spectacle and intimacy — a Las Vegas holiday show built to feel warm and widescreen at once.

At the centre of the evening, Mariah Carey delivers the kind of vocal warmth and showcraft that made her a holiday touchstone. Backed by lush arrangements and a tight ensemble, she moves from tender, torch-song moments to big, jubilant choruses with ease — each song given room to bloom and each chorus designed to land like a seasonal revelation. The result is a residency that’s both soulful and celebratory: holiday classics reshaped with care, plus the moments that remind you why Mariah remains the voice of the season.

Dolby Live at Park MGM is the perfect stage for this run — compact enough to feel intimate, refined enough for widescreen production. Las Vegas at this time of year is its own kind of set dressing: Strip lights, late-night energy, and an audience ready for tradition and spectacle in equal measure. For fans in town this December, check door times (Dolby Live lists doors at 7:00 PM, show at 8:00 PM for the residency dates) and expect a polished, late-evening holiday set that fits the season.
