Hmmm, now I am questioning this. I have not made final payment yet. SO I just called and cancelled the PLUS package. I had received an email from Princess that 'looked' like they were now including everything in the 'Sanctuary'. We are in a Penthouse Suite too. But I might not have fully understood that email. I was already getting all the Sancturary perks - that's why we booked the suite in the first place. I just sent an email to my TA asking for clarity. I'll report back.
But how in the world will they know who is and isn't Premier if all suites sold from this point forward include the Premiere package?! On Celebrity - if you are on the Retreat Deck, you have the package. There aren't some with and some without.
