We were honest on our recent cruise on Britannia and having covid 3 days into the cruise we missed all ports ,being isolated for 7 days. It is disgraceful that the P&O policy encourages peoploe to blatantly lie about covid or any non infectious illness. I often get a cold as seasons change and believe me I would now lie. I cannot believe P&O because if you answer no and embark on the ship coughing they will ignore it. I hope you are successful in your actions and we are considering legal action also, althoough slightly different.
