This bar menu
is a couple years old so add 25 to 50 cents to most prices and you'll have an idea of what the costs are. Bottled water is extra. The juices, tea, coffee, and of course tap water, are included in your cruise fare. Cruise ship tap water is perfectly safe to drink. Often they will set up an ice water station by the pool bar for self-service. But you can always ask a bartender for a glass of ice water. Just remember that while iced tea and juices are "free" in the buffet area if you ask for them at a bar they will charge you. Water is the only freebie you can get at a bar.
Oh, and welcome to cruise-chat! We are happy you stopped by and I hope you will post more questions and comments.
