When I did the math on an 11 night cruise it came out to I was going to be spending 47 cents more per night with plus. But, in addition I also got 200$ in onboard credit. So I came out ahead with getting plus. I am not really a drinker, but on NCL I get free drinks in the casino so I may have 1/2 per night plus bottled water (I will get all of this with Plus on Princess). I have never sailed on princess so I won't be getting that casino benefit. I always buy the soda package but I would have at least gotten the coffee card if not the coffee package for Alaska. I have loved cruises to Norway, and the Baltics, but Iceland is cold even in the summer a nice warm drink when you get back on the ship is something to look forward to.
