If it is similar to last year....80s night, there was a dance party with ship professional dancers performing hits from the 80s in between opportunities for us to dance to 80s songs and then the CMs use participants to highlight memorable moments from the 80s.....70s night there has traditionally been a Gloria Gaynor lip syncing contest and a GoGos vs. Bon Jovi band playoff with audience participants (as well as some 70s music to dance to).....60s night started last year with the live band playing Beatles tunes to dance to and also showing some film of this era.
When the CMs really push the audience to participate, these nights are great whether you are dancing or just watching!
