I almost never buy packages that include alcohol, because I won't drink enough. The odd one out is my upcoming Princess cruise, where it financially made sense to buy the Plus package when I'd already be paying for WiFi and crew appreciation and possibly a soda package or non-alcoholic package. On Carnival, I usually don't buy any package because they don't offer a non-alcoholic option aside from the soda package, and I like mocktails and specialty coffee.
