Are there enough activities on the Princess Crown to keep young adults busy?

We are interested in taking 6 of our grown grandchildren (ages 18 - 22) to Alaska in 2023.  I don't like the look of the mega ships, and the Crown is my favorite size of ship.  I was wondering if there are enough activities to keep the kids busy on sea days?   I think they'll be fine in the evenings, but what about during the day? It's too cold for the pools.

My grandkids are 21 and 24. They enjoy Princess daytime activities. Trivia, movies, games, lectures, crafts etc. They can attend any and all adult activities. Of course in Alaska there is scenery and excursions on port days.
