I know Quintess members and I can guarantee $10-15 mil net worth is not accurate. Quintess has no way of knowing anyone’s net worth except by survey and let’s face it, people either exaggerate or under report because they don’t think it’s anyone’s business to know the exact range.
As for ResidenSea, ER just remodeled all their units onboard and there have been some other updates within the ship. It seems to be very well maintained.
