Question about 3 day itineraries

I have a question about 3 night cruises. I've only done cruises that are 5+ nights long, but I am doing a 3 night cruise in November. My question is, do the shows like the Broadway shows, the aqua theater, the ice shows only play once, or multiple times? I am mostly asking about the Broadway shows as they are my favorite part of RCCL. All my past cruises have been 3 showings- 1 day with two shows and 1 day with an evening show. Is there only one showing for shorter cruises? Thank you!
