This may be a ridiculous thought but...

My wife and I are 60ish. We have just discovered our love for cruising the past couple of years. We have been on 5 cruises.. but.. I have gotten pretty sick on everyone of them. I have taken many precautions like taking vitamin C several days prior. I am up to date on immunizations. I wash my hands religiously. I am in good shape. We don't do the buffet much. We have done basically the mainstream lines. Usually, about halfway through the cruise I get sick. I have gotten Covid 3 times and the flu twice. I am usually sick for about 10 days.

I am happy with the mainstream lines but I am thinking I may try Princess, HAL or Celebrity in the hopes that fewer kids may mean less chance of illness. What is everyone's thoughts? Is this just wishful thinking?
