Adventure ocean is split up into 3 (maybe 2) age groups, apart from Navigator which is now all combined, 3-5, 6-8 and 9-11. Some ships and some sailings combine the older 2 groups.
There are 3, 3 hour sessions a day (although they are open all port hours). Each session will have a different theme and different games, activities, crafts and science to go with it. Unlike
DCL there aren't specific times for activities, more of a, this will happen at some point in the session.
There aren't really electronics and if there are they're only really for free time, usually 30 minutes or so at the start of the session. It's an activity based program, unlike Disney's free for all, so if kids dont want to do the activity then there isn't usually much else for them to do, maybe color or read a book or play a board game, but not much.
I feel kids make friends easier/quicker on royal, as well as getting to know the staff and the staff getting to know the kids.
For some kids it works and they love it. Others hate that it's so structured and would rather Disney's clubs.
