@silverwoman I personally have ruled out cruises, not only because of the food, nut even more so because germs on cruise ships seem to travel and cause heavy outbreaks. Being on immunosuppressants we are so much more likely to catch something. We went to NYC in December of 2017 for my daughter’s wedding celebration and afterward I ended up having Legionaries disease. I could have caught it elsewhere over the weekend but the person who called from the board of health and I both thought it was probably the venue. No one else got sick though, nor did anyplace in the city have an outbreak of legionnaires. We are just much more vulnerable than the general population.
I do think I might one of those European river cruises mentioned by @jolinda
