I'm not sure if anyone here would have that percentage. Are you wondering 1. Can I get the one I want? or 2. How empty will the ship be if I don't go on one?
There are a lot of people who get off the ships and take their own excursions. I did but I wouldn't know the percetage of that.
Life is too short to let the ship of your dreams sail without you.
