Thanks for your reply Dusko, I will be sailing with Princess cruises and I embark in Cape town, South Africa & Cape Verde is one of our ports. I received an email from what I think is Brussels embassy Cape Verde he said every visitor has to register with 'Ease' and the cost of the Ease is classified as airport tax, but surely if I am arriving by cruise & have already paid the port tax? I have not received any advise from the cruise line via phoning or internet or through my booking. I have a friend who is onboard ship now luckily, she's my inside contact, I'm still waiting a result from her enquiries. Look like I will apply for the Ease nearer the time, just incase things change..... Enjoy your Seabourne cruise, cheers 🥂
