We are booked on QV Madeira and Azores in Oct 25.
Madeira should be OK, we have had many land hoidays there including in October, and December, January when the weather is still fine and not too hot.
We booked hoping to visit the Azores which will be new to us. The weather, sea conditions can be uncertain at any time of year.
@Bell Boy, we were on that QV cruise. We were denied entry to Cartagena, Columbia also because of covid precautions. If memory serves, that was replaced by Curacao. Then after disembarking American pax at FL it was straight across the Atlantic post haste to get to the UK with no further port calls, omitting NY and the Azores and terminating at Southampton from where German pax and others had to fly home instead of continuing by ship to Hamburg.
