Here are the latest recommendations on the restart of cruising. I think with these restrictions people will think twice about booking a cruise while the virus is still active. If the cruise left from your home city, it could work. If you need to take a long flight, perhaps it's better to wait until the virus is gone or everyone is vaccinated.
When things go back to normal, I will cruise again! My March Australia/Asia cruise looks doubtful. I love cruising but I'm not about to fly for 15 + hours to have these strict restrictions. I am hoping my Alaska July 22, 2021 cruise will be safe to sail. It will be much easier to get to the ship when it docks at Canada Place.
Destination Canada is looking better all the time. This is a beautiful country and it's time we stayed close to home.
