Pacific Princess had a dedicated "children's playroom". There were 5 children (from two "related" families).
The children's playroom was located on deck 9 next to the Internet room and across the "hall" from the salon.
The deck plan
still shows that room as the Card Room.
You will also find a smaller casino.
Yes, of course. It's a smaller ship, so there will be proportionately fewer passengers using the casino.
There was no crap table.
I wasn't aware of that until you mentioned it here, but I can see why. Renaissance probably had to choose between Craps and Roulette because tehre was not enough room for both, and Roulette won. I doubt that Princess has reconfigured the casino since taking over the vessel.
