We actually booked inside cabins and for the 5 of us, 3 cabins came to about the same as a cabin for 2 and 3 due to the significant increase in price for the third person. The only issue is that you are closer to your cruise and there are fewer cabins available. Also, you may need to put one adult and one child (even though the oldest is 19) in each room, at least on paper. We had to have my oldest who is also 19 in a connecting cabin or immediately next to us to be able to book the cabin. Good luck! I hope you can find a way to book another cabin- I think you will be a happier family that way. The suggestion of an interior and a balcony was a good one if the price works out?
