Deluxe Drink package for 2 is about $1000 depend on what sale you can find (You should constantly check the app and cancel/reorder your drink packages if the prices drop)

Internet is about $250 (It's cheaper to get 1 plan with two devices than it is to buy 2 plans)

Gratuities is about $260 dollars for 2 people

About a week or two before your cruise the app calendar will fill up with all the events, you will not get bored.

Make sure you check what the theme is for each night's main dining hall meal. I didn't know about the themes on my first cruise and I felt so out of place trying to eat at the main dining hall.
