I'm cruising in September, also in the UK. I've been online to see about upgrading and there is no option to upgrade the pre-14 December plus package to the new version - it just lists all the elements (including new ones) and says "purchased". I do have the option to upgrade to premier (not worth it for me). I'm therefore going to print this and take it with me. Will advise of outcome on return!
Incidentally, I am just back from a cruise booked in July 2022 and I also got the free gelato when that wasn't meant to be included. I only got this once and didn't try to get juice or attend a fitness class. I saw others being advised that the gelato wasn't included for them when they asked but not sure if they were on standard or plus package. This was on Sky.
