Can someone explain how the non-alcoholic drinks affect the signature drink package? What size are the cokes they bring you? If you get a coke with your lunch and have two refills, does that count as 3 drinks against your 15 / day limit? I wanted to upgrade to the elite to avoid worrying about it, but see per @jewel 14 post above that we cannot do that until on board and that it will be $11/pp/pd vs the $5 difference shown between signature & elite package. And do they count the least expensive drinks up first and then if you go over 15 drinks they charge you for the most expensive or do they charge only after 15? DH drinks a lot of diet Coke, but will likely also have some beers and some scotch, so he is worried about using up his 15 drinks on the diet Coke.
