Let's keep the jogging concern in perspective ...
1) This is Holland America my feathered friends. There are not that many joggers.
2) Unless they are slapping the deck with giant clown shoes, they're not going to make that much noise.
3) Holland America is a (fairly) professional business concern. They actually do study concepts before they sink funds into projects of this magnitude. If the Lanai cabins have such inherent faults (noise and/or privacy), the word would quickly spread through the TA industry and the passenger community (thanks to Internet forums, like this). In very short order, Lanai bookings would drop to almost nothing and the fleet would be sailing with many empty cabins. ... Not going to happen!
