OK I'm on the computer now instead of my phone.
You're looking at Replenish. That's soda, bottled water (not Evian for the drinks packages), sparkling water, espresso and fancy tea drinks from the espresso stands onboard (including fancy hot chocolates, frappucinos, etc), fresh squeezed OJ at breakfast, and non-alcoholic cocktails (so frozen virgin drinks and things like that). You can see why that package is 19/night plus 18% tip (the tip is plunked right onto your purchase price of any of the drinks/water packages...no extra tip at the time of ordering a drink is needed).
If all you want is soda, look at the Refreshment package, which is 4.50/night for those 17 and under, and 6.50/night for those 18 and up.
If you want bottled water, you can buy a water package, which gives you 1L bottles of Evian, delivered to your room. $39 for 12 bottles and $69 for 24 bottles.
If you're on Vision class, and not in a suite or panoramic oceanview rooms, you will NOT have a fridge, however, so that water will need to be consumed at room temperature.
The
water packages can be shared (the case or two is/are delivered to your room and stays there), so if everyone is big into Evian, go for one of those, if the other packages don't work for you!
