I have been able to do this successfully by calling Captains Club. I am sailing with a group in April and there is 1 adult and & 4 underage that would not be drinking but wanted access to the extra options on the Zero Proof Package. The agent was able to easily do this for all who wanted but no refunds were given for the price difference. Their Express Passes immediately reflected the new drink package as we are already checked in for our sailing (“PMNA”). Here is the number I called: 1-844-418-6824. It took forever to get a hold of someone but you can request a callback which is what I did. The representative was super helpful and took care of it right away. Hope this helps!
