I don't believe the bartenders are tipped based on the drink you buy with your package. To make the math easy, let's say 100 people buy the package and there are 10 bartenders/servers. So, if the daily gratuity for the package is $11.68 per day, that $1168 dollars in the pool. Divided by 10, that's $116.80 per bar person each day. So that's $817.60 per bar person for a 7 day cruise. It would be an accounting nightmare if they had to break up the tips from the package based on the cost of each individual drink.
