The lounge is also used for pre-scheduled events by the Holland America Line's enrichment program, which includes daily dance classes, trivia games, cards playing, karaoke, HAL Cats (8-piece party band) performances, live grand piano performances (in the afternoons and evenings). Crow’s Nest becomes a disco (dance club) at night, with live DJ music and dance contests. During the ship's last refurbishment, the Crow’s Nest bar lounge was renamed "Explorations Central" and its interior was redesigned.
