I would vote for a NS and an across-the-hall inside. A verandah cabin, which, BTW, is larger than Princess's balcony cabins, does not give enough room for family time. The NS is much larger and has a much larger balcony. OTOH, how much family time in a cabin does a family usually enjoy? Family time the teens get at home. On board ship, I suspect that togetherness may be more limited.
