5 night Fantasy vs. 3 night Wish+ parks?

Having trouble deciding between a 5 night Fantasy sailing to Nassau, LP, and CC vs a 3 night Wish with 3 nights at WDW pre-cruise.

We have done the same itinerary on the Fantasy in concierge (last minute port upgrade ftw!), and are worried that has spoiled us. Would be sailing as 2 families each with 3 young children including 1 year olds. The cost is the same per night for Wish, Fantasy, or WDW at Port Orleans Riverside in a Royal room including park tickets and dining plan.

We have already seen all the shows on the Fantasy, so it would be nice to see some new shows on the Wish. But I am concerned from what I have heard about the Wish that a 3 night may feel chaotic and not relaxing. What would you do?
