- Mail and package forwarding service with port-aware address rotation and customs pre-clearance

True full-time cruise residents (not buying cabins on residential ships) are a tiny niche; Villa Vie Odyssey reports only a few dozen onboard residents, Storylines hasn't launched, and the broader 'live on cruises' lifestyle community is likely only low-thousands globally — far below the scale needed for a standalone product.A year at sea: The reality of living on a permanent cruise - CNN ↗You Can Live Permanently on a Cruise Ship!
