Headlining acts perform in the "Donny and Marie" Showroom. The throwback venue was remodeled in 2014 that included many technological updates improving the sound systems and lighting. It seats 780 with floor seating and a balcony. It maintains the style and feel of early Vegas with red and white themed booths and chairs, red velvet curtains as well as red carpets. It provides for close intimate interactions between the performers and audience due to the clam-shell layout. It was officially named the "Donny & Marie Showroom at Flamingo Las Vegas" after the Brother and Sister duo that headlined for an eleven-year span between 2008 and 2019. Starting late November 2019 the “Donny & Marie Showroom” went back to its original name “Flamingo Showroom”.
