I called in Feb or March for our March 2023 sailing. We had the all-included so Classic package. My husband doesn’t drink so was hoping to upgrade mine and was happy to move him to the non-alcoholic package if they required it. They wouldn’t or couldn’t do it - honestly not sure if system wouldn’t let them because a couple different reps tried to help. Either way I couldn’t upgrade just one 🙁. It worked out okay though because drink service ended up being lousy on this particular sailing so I didn’t drink enough that it would have been worth it!
