Father on Hemodialysis - how do I find out about Vancouver origin dialysis cruises?

This summer, my family and I would like to take an Alaska cruise. There will be several family members of an extended family - some living in the Vancouver region, and some living elsewhere in North America.

My father, who started hemodialysis a few months ago, and who is a physician himself (as I am), lives in Vancouver.

So, we would like to book an Alaska cruise for either July or August. How do we find out about such "dialysis cruises"? Do we book through our travel agent, or through a special cruise travel agent dealing with dialysis cruises. Is there a web site where a list of dialysis cruises for each region of the world are listed?

I don't know of any cruise specifically arranged for Homedialysis.:mad:
