I have always found the dispensers in the various dining areas are very good, you can usually get orange; punch and a form of lemon ade. I would go for the 330ml and 500ml bottles some fridges in your stateroom might struggle to take a full litre bottle without emptying out some of the contents to make the space. Outwith dining times the dispensers are sometime difficult to find but I have always found one that was working.
I think tea, ordinary coffee, fruit juice in certain areas are free; everything else is chargeable.
Coffee, tea, and milk and water are Complimentary onboard all ships in all lounges except for Cova Cafe.
Yes ...like they said except that the "juices" are available at meal times in the restaurant and cafeteria areas and they are not juices per se. They are concentrates with added water, most times too much but that's my only complaint about Celebrity. I realise that it is easy to run up a large bill with extras so if you are really bothered by that when you go ashore bring back 1 litre bottles of what ever fizzy you like and keep it in the fridge don’t get a larger bottle because they won’t fit in the fridge.
