My question relates to drinks packages and the insistence of most cruise lines to have all members in a cabin have the same package. My husband and I travel with our adult daughter who has a congenital disability and cannot drink alcohol, but we have to buy her a full package even though she will only drink juice or Coca Cola. We enjoy a tipple especially as we don’t need to be concerned about driving but the cost becomes prohibitive on longer cruises and we don’t receive value for money. If Celebrity cruises can differentiate between the guests in a cabin, why can’t the other cruise lines do the same?
