I am an infrequent cruiser and am currently debating whether to buy the drink package for an Alaskan cruise this summer with Princess.

This site shows that I would save about $100 based on a consumption level that is somewhat generous but not necessarily unreasonable for a vacation.

I enjoy moderate alcohol consumption but wonder whether a pre-paid package becomes an incentive to drink more than I might otherwise.

For those who have bought the packages did it cause you do drink more? Does the 15 drink per day limit become a target to meet instead of a restriction? Does anyone regret buying them? Do they encourage irresponsible consumption by other passengers?
