I always like to take a picture of any ship I am on and more so when I am walking back to it because it marvels me that such a big mass of metal can stay a float and travel such great distances.  Ships have come along way since I was working as crew 15 yrs ago.  That was before the mega ships that are now.  Since I researched my Mothers side of the family and read lot of how the ships were in the 1800-1900's, it is amazing.  So I will always have to add the ship.  This one carries around 3500-4000 passengers alone not to mention crew.
