I hope this may be helpful. Attached is the link to the current 2022 Princess drinks price list. Almost all of the drinks are within the $12 Plus limit. If you are buying the premiere package for the drinks alone then I expect it is because you are a connoisseur and enjoy really fine wines and spirits. If, like me, you are not sophisticated in your drinking habits then to me it’s not really worth it.
