Yes. I always bring on a 12 pack of Diet Coke at least to have something that I like in the cabin. While out and about the ship I tend to ask for Diet Mtn Dew, but as stated they tend to run out at certain bars. If I'm looking for a mixer I tend to use Starry Zero. I don't like it plain but with some cherry vodka and a lime in it, it'll do 😉
