If you have a problem with kids why haven't you booked on an adult only ship? I would have thought MSC would be the last line you would consider - as kids travel free I would guess there will be quite a number on board.
What were you expecting: that the children be kept locked in cages? Or that the children be kept locked below deck - with the cargo or like the 3rd class passengers on the Titanic???? Contracting the norovirus sounds like a more enjoyable holiday then spending a week with folks like you.
Ive just returned from a week on IE for the 4th time like yourself and your comments are totally pathetic ,children are entitled to go on holiday ,i think IE will be better off without people like you good riddance .
