Breakaway Entertainment on 12 day cruise?

[Red-Sol]

We sailed the Breakaway to Bermuda last year and just loved the ship. We are thinking of booking the 12 day cruise to Southern Caribbean in January 2015. I was wondering how/if entertainment options might change on a longer cruise. On a 7 day you have multiple showings of Rock of Ages, Burn the Floor, and the Magician in the theater. But what happens on a 12 day? Do they just have an increased number of these same shows..or do they possibly do something different? Other types of shows perhaps?
