I'd like to know if anyone has purchase the SBUX package and used it? We do not sail till April 2023 on the Epic with our two daughters (13 &9) and they love the Frappachinos and Freshers. So I would really want to know is if I can purchase this package for each of them and not obligated to purchase it for my husband and myself? This would be a way better deal for my girls since they do not drink soda and would easily drink 2 or more SBUX drinks a day
