We were told that there were 2088 passengers on the cruise, and that all except three or four hundred were US citizens. Of course, many of the non-US citizens were English speakers, though we heard some Spanish and French spoken on board.
The passengers included 104 children, but they were relatively inconspicuous and didn't seem to cause a nuisance.
Among the adults, there were more old than young people, but the age distribution wasn't extreme. Like the children, they seemed to be well behaved.
