We did the Hawaii cruise in January of 2023. They had many "extra" activities on the sea days: lei making, Hawaiian language classes, Hula classes (daily), ukelele classes (daily), Zumba, ballroom dancing, lectures about the Hawaiian islands and culture, caricature drawings, cooking classes, and other things I've probably forgotten. We stayed quite busy!
The other two cruises you mentioned are also good ones, but the Hawaiian cruise was something special, for us! (We are Diamond, with Carnival, so we've cruised often, FYI).
