I would like to know the answer to the above questio.
Dont know any UK based cruise lines that do, but Deter deilman certainly do.
The National Kidney Federation Website on this link http://www.kidney.org.uk/holidays/dialysis_cruises.html has a number of option.
Visit www.dialysisholidays.co.uk they are a company specialising in haemodialysis cruises based in the UK. My friend booked through them and said they are really helpful and professional.
