Is it the same on all of the NCL ships that have this as a feature?    We were on the Prima which is a smaller ship than the other NCL ships that have this. Other than the Rumours concert, you could get in coming at the last minute (though not a seat). In fact on the first night, we came after it had started and still got in.   If it is the same size on the larger ships does it make it even harder to get in?
