@superduper123, we booked early last week while onboard a cruise and got the 60% off for 2nd passenger, and AI was included. This was an April ‘23 cruise. If you are booking on your own using the website, it will show you if it includes the AI. If the itinerary includes AI, the sale doesn’t impact AI inclusion. Just check it as you pick.
For us, we do use a TA and had the reservation moved to them and they were able to rebook using a Group discount which gave us further savings. And yes, there are plus/minus of that. Booking on board only cost $100pp deposit. To use the TA group booking, had to use the $500pp deposit. We don’t worry about deposits that much since dont make changes a lot.
Good luck, and just double check with the itinerary you pick that it includes AI.
