Yeah, Princess plus is $65 and also includes internet (plus all that junk nobody wants).
We are only doing a shortie on Carnival to use up our cancellation credits, with lots of cancellation OBC to cover our drinkies. Like P&O they need to be 7 nights to get the drinks package, but we have never bothered with P&O's either - too dear.
There are plenty of cruises ATM, where the drink package is more expensive than the fare. Crazy, and a good reason to become a tee-totaller. Yeah-nah! 😂
