Obviously, this Forum is focused on the subject of sailing and cruising on our own vessels . . . being "master of my domain" as made famous in an episode of Seinfeld.
However, that isn't going to forever and always work for all members. It doesn't mean, though, that they can't still enjoy time in the tropics, visiting the various ports
, being close to the sea.
The cruise ship
companies have actually put together cruises for individuals in your position, Lexam. Their ships are equipped with dialysis machines and trained staff to provide the treatment you require right on the vessel. You can enjoy your cruise
just like any other passenger, without worrying about your health
I have no specific recommendation, but a Google
search should provide information on these types of cruises.
Good luck, and good health!
