If you book a guarantee verandah for 4, you will have the queen bed, a bed that drops down from the ceiling, and the sofa will turn into a single sofa bed. If you get really lucky and end up getting assigned a family verandah, in addition to all this you will also have a pullman bed come out of the wall that would then accommodate 5 in the room. Regardless, your two kids will each have their own bed and will not be sharing.
