From Celebrity's website: Celebrity's soft-drink program has been established for all guests onboard to obtain soda drinks at a daily rate of $5.00 plus 15% gratuity.
The purchase of the package should be for the entire cruise and not on a daily basis. In the event the purchase of the package is not made on the first day of the cruise the guest will be charged for the remaining days of the cruise inclusive of the purchase day.
Packages are available for purchase in the Plaza Bar (Horizon) and Cova Cafe (all other vessels). After the package has been purchased, a soda sticker will be placed on the guest's signature account card.
Guests with the CoCa-Cola stickers can obtain sodas from all bars throughout the ship and with exception of room service or the mini-bars. The sodas will only be served when the guest is present and one drink at a time.
In the event a guest loses their signature account card with the soda sticker, a new folio number has to be issued together with a new card and soda sticker.
There are free 24/7 fruit juice dispensers throughout - lemonade, iced tea, guava, and punch.
