Anything could happen, but it is likely we will have more variety shows and the formal nights on the sea days, from my past experience they are unlikely to have a formal night on the Panama day, as it takes it out of you, its hot and steamy.
You might have a Disney 'highlights' show with bits from all of the shows, old and new, basically as it comes to the usual cast.

Upgrades of Karaoke, and passengers talent shows to a main show, plus kids talent as well, (usually rushed on the last day after Castaway cay).
