We are sailing on the Liberty of Seas next week and going to Jamaica. I've been told various things about "drink packages"! Would appreciate any help with information. I'm told there are "cans" of soda available in your stateroom refrigerator for $1.50/can. We can also purchase a soda card and carry a cup around and get it filled anywhere at anytime (probably waiting in lines each time?) Does anybody know about the soda in cans and the exact cost of them? We want to have it in our room. We are told if we get room service to eat on our balcony, it will not include soda? Can anybody help us out with accurate information? Thank You!
