We sailed on the Summit which is carbon-copy of the Constellation with a 5 & 6 year old and they had the time of their lives. The Fun Factory is a huge playland with ball pit, row of Nintendo games, huge craft room, big screen tv for movies. The good thing was the counselors are very well trained and they don't let the kids camp out on the video games or tv all day- they'll take them on scavenger hunts, play games, read stories, have their own art auction with their parents and do all kinds of fun activities. I think they're grouped 4-6yr, 7-9, 10-12, 13-17. My kids were in the youngest group so they did lots of arts & crafts, puppet shows, etc. while the 10-12 group probably has more activities geared toward that age group. Make sure you go to the first night meeting to meet everyone and get your kids feeling comfortable. Have fun- the Fun Factory absolutely saved our vacation, gave us a little bit of couple time (for free!) and the kids had a blast.
