Good to hear that you are doing well. I cruised with my mom (I have lost track of the number of times or just with one or both of my sons) for a long time before my husband finally came on board. Now, he too is hooked. You are right to start your husband off on a 5 day trip. Just a reminder, because you have been ill, to make sure you buy travel insurance. I am a big advocate of insurance. As long as your illness is stable, you should be able to get coverage - trip medical and trip cancellation always a must. Cheers.
