It’s definitely not being forced on anyone (I was told it never was-or at least on my ship) and they have not forced siblings to split up if they don’t want to.
DCL does not want 11-12 year olds out of Oceaneers, they are trying to find a solution to many of them either not wanting to go at all or saying they are bored with minimal programming geared to them.
No one is sure how long this will be in place for or if/when policy will actually change. I am sure that DCL will not change this without doing due dilligance and asking for feedback from kids, parents, CMs and Managers
