welcome to the forum.
We have sailed on the Zenith last year and drinks like coke, sprite cost about 19,95 plus 15 % service charge.
Thats why we decided to buy a soda package for 6 $ per day. And in contrast to RCCL, we got original coke or sprite. On the Splendour last november we got only sodas from an automat at the bars, so not the same quality.
Cocktails are about 5,95 $, beer about 3,95 $.
Included are icewater and icetea for dinner in the diningroom, in the selfservicerestaurant additional lemonade and orange juice and of corse, coffee and tea.
