Yes you will be able to take your son in the main dinning room if you have booked freedom dining,not sure about club dining .Don't forget that he will need a suit for formal nights!I'm not sure if the pools are 24hrs but the kids club open untill 11pm.Have a great time ,my children really enjoyed it.
Kids can eat with you in all dining rooms, they will have been included on table numbers when you booked, our children ate with us most nights, they do need to follow dress code each night but that's the same for all people over 13yrs and where ever you eat. pools seemed to be open most of the time.
A fourteen year old does not have to wear a suit, although lots like to join in, however, reading the small print in the P & O brochure: passengers between the ages of 13-17 should be dressed in at least smart casual (no jeans)on formal and semi-formal nights.
At last someone that enjoyed the ventura, we are a family of five, children aged 17, 15 and 12 travelling in august next year and i was beginning to wonder if this would be the holiday from HELL.
Yes, your son will be ok to dine with you and on formal nights many wear things like a blazer and flannels and my nephew thinks it's very cool to wear a black or coloured bow tie.
I would caution you about using the pools and or the Jacuzzis when no one else is around there is a large element of risk attached to that. The staff do close the pools overnight sometimes for maintenance and quite frequently if the seas are rough ... regards ... Neil
