The tour kicked off with a show at The SSE Hydro in Glasgow, Scotland on March 15, 2016 and concluded with a show at the Neal S. Blaisdell Center in Honolulu, Hawaii on November 26, 2016. The tour saw Carey play six venues across Great Britain and various others across Europe, as well as several dates in Africa. The Sweet Sweet Fantasy Tour is Carey's first tour to visit the European region in 13 years, the last being the Charmbracelet World Tour in 2003. It is also her first tour to visit Hawaii in almost two decades.
The tour's set list was noted by fans for including songs rarely or never before performed by Carey, such as "Loverboy", "Against All Odds (Take a Look at Me Now)" and "When You Believe". "I Know What You Want", "Obsessed", "It's Like That", "Shake It Off" and "Loverboy" are one continuous medley.
