sika ye mogya

Was just wondering about the Drinks package with RCI. We have many kids with aged below 9 years downwards. Eg: 1 year , 5 years , 6 years, 8 years . They share stateroom with there parents. How's are the Drinks package calculated. OR Do the kids share from there parents package, since they don't consume much soda's. Do we only buy the drinks package for the parents and the child share with the parents the same package . I would like to have this clarification as we are now about to book the Drinks , shore excursion, internet, etc ... With best regards Mirpuri
