The MV 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.
You will also find a smaller casino. There was no crap table. The slots were penny, nickel, quarter, and dollar, but there were no bar, bar, bar, 7/7/7 or poker machines. They are the more "gamey" x lines, by x times with a theme: Boot'n Scoot'n, the traveling penguins, Cleopatra, etc. very different than what I was used to.
