On 10 September 2018, we watched Mariah Carey's concert residency, The Butterfly Returns, at The Colosseum at Caesars Palace in Las Vegas, Nevada, U.S.A. It was the last night of Mariah's Las Vegas concert for 2018. The Colosseum has arena-style seating & the acoustics were ok. The ushers were also helpful. However, Mariah was more than 30 minutes late. Her performance, in my opinion, was unremarkable.
