Re the Canaries Encore cruises announced, does anyone have the answers to these questions please?    1.  What will sailing occupancy be? 2. Are passengers again required to be fully vaccinated? 3. For UK cruisers, does anyone know the current vaccination/testing/entry requirements for these cruises and does anyone know whether the Indian made AZ batch numbers are permitted for Portuguese/canaries travel? 4. Million dollar question - will passengers be allowed ashore indepen
