If I was cruising, Id only go to Palo for brunch.
Personally, I feel that Lumiere's is the least family friendly (but its not, not family friendly), its the least naturally fun.
Cariocas is brighter colours and they make you napkin hats, which is often fun for kids of all ages (but I get some people don't like that)
However, I personally prefer Lumieres menu, but it depends what you're into.
As a CM, if we were granted a dining request, we then had to go and talk nicely to see if a restaurant then had a space for us, we would always go to Lumieres first, Animators, then Cariocas. But we never didn't enjoy Cariocas, and if the choice is that or mess food, it wins 1000% lol.
However, Cariocas and Lumieres share a galley, so if you go to one and not the other but theres something you really want to try from the other (on the signature menu), its pretty easy for your server to get it for you to try if you ask nicely. (the second time I ate in cariocas, Lumieres had been full, our waiter encouraged us to order off the Lumieres menu if we knew what we wanted off it)
