Can you imagine the kids climbing down from the uppers with a bed in the middle of the floor? My friend wanted us to cruise with his folks in one cabin and I decided I would have refused to go in that case. Maybe get adjoining cabins if you can afford it. Just remember too, what it will be like to share the bathroom. A schedule would have to be made for showering and dressing. I was lucky as I was an early riser, did everything while my friend slept. I saw a pic on someone's site that showed a rollaway sitting in between the floor beds, which the steward would put away in the morning. But that would only accomodate 1 child. You have a tough decision to make.
