What is the largest passenger ship in the world by gross tonnage, as of 2019?

When you cruise on a large ship, yes you are on the ocean, but it feels like living in a town or high rise apartment. It is not at all like being a a private boat or large yacht.

RushMama2112, wait till you all want to get off ,you just flood the place you came to see and low and behold there’s four or five cruise ships coming at the same time don’t bother going

I sailed on the Norwegian Bliss last September. It's HUGE!! Can't imagine the size of the Symphony.

Player #48458, I got it right after thinking a minute!!

Player ccbkd, never heard of this line is it a passenger cruise ship
