With 5 people, I would go with two rooms. DH and I shared a category 4 this past Christmas and loved it. However, there are so many options for being outdoors that the trade off between space and outdoor verandah simply comes out in favor of 2 rooms, IMHO. The coffee station on deck 9 is just as good as a verandah for early morning coffee and muffins (and there is no dress code - pjs and robes are fine.)
We have booked a category 4 again for next December, for DH, DD, and myself. Anymore than 3 people, though, and we would be in two inside rooms.
