We wnt on a 10 day cruise on QV in April. About 70% of passengers were British and the reamainder were a mix of Americans and other europeans. We are both 50 (but young at heart!!) and I would say that the average age was probably nearer 60 but there were also a few families with children. We were NEVER bothered by the children and they seemed very well catered for. This might be different if you are travelling in holiday season! Be aware that Cunard do enforce their dress code. All in all we had a great holiday on a fantastic new ship with traditional decor and food and service second to none!! Michael.
