Bit of an update. I've just downloaded the new Princess app and set it up with my cruise details. On the front page, to the bottom right, there is a section marked 'profile'. I clicked on that and amongst the many sections it brings up was one called 'package'. I clicked on that and it listed all the items included within the premier package, including the missing ones.
I suspect(hope!) this means that the full premier package is on my account, but it does not say words to the effect 'this is the package you have got', though I think that is the intention.
