When we went in 2019, there were 12 of us across 4 cabins (5 kids and 7 adults). The kids have never been on a cruise and several adults had not.
We did the full package for three of the rooms and the fourth room just showed up in our pictures. It was 8 nights and I feel like we spent a lot of time waiting for pictures.
In the future I think it will depend on the ship and who we are with whether or not we go for a partial package. For example, next month there will only be two of us and I don’t plan to do any pictures.
I was able to create a really nice memory book in Shutterfly with our pictures From 2019 though, so ultimately I think it was worth it for the first time.
