I took my children on the Fantasy when they were 3&4 years old and we all had a marvellous time. I think the trick to taking young children anywhere is to know their limits and to act as a responsible parent. We fed our children in our room using room service around 5pm, put them in kids club and then we went off the late seating dinner & shows and didn't disturb anyone. The kids had a great time and so did we. When we picked our children up from kids club, we went back to our room with them. I do agree that children running around in lounges at night can be quite annoying. Our children are now 10&11 - we will be cruising on the Victory at Christmas time - and their manners are impeccable. They have been taught, from an early age, that running in halls, slamming doors, screaming etc. is not acceptable. Children will naturally act responsibly if their parents do the same.
