Hi Skee,

I was on the Royal Princess for a Panama Canal Cruise in February of this year. The only chips in play were generic "Princess" chips and a lot of $5 Millennium Chips that listed all of the ships.
I asked at the cage and they said they had never used chips that were unique to one ship only.
Sorry I could not be of more help.
