If “passenger” means “paying guest” then the ship is designed for ~5600 with two in each cabin. Most cabins can hold more - so the maximum capacity is closer to 7,600 (which is probably more a measure of what the ship can support with meals and activities rather than the number of bearths)

Add the 2,300 crew and it could occasionally sail with just under 10k people onboard. Which would count as “passengers” in the sense of “number of people on the ship” rather than the traditional sense
