Covid travel restrictions and requirements

Will the itinerary for my cruise change if there is an outbreak at one of the destinations?
We are calling and speaking to our destination partners regularly, and will be closely monitoring the situation in any destination that we are due to call into.
I have been asked to travel with a smartphone or tablet – why is this?
We recommend you bring a mobile phone or other device on which you can read your emails and show vaccine status QR codes as you may be asked to show proof at the ports of call on your cruise.
