Fastest growing industry for holidays - esp with children. RCI are considered to be the best for kids [that is why i avoid cruising in school holidays] - ice skating rinks, flowrider, rock climbing walls, in line skating, mini golf..
I have booked to go on P&O's new ship Ventura with my family they have Noddy onboard and also Scalextric. I have also heard that they are going to have a 3D cinema.
I also went onboard Sea Princess 2 years ago and my family enjoyed it very much.
Kids love cruising, there is so much for them to do.
