And you shall do all of those things.
I'm sorry to hear of your loss; sometimes such events awaken in us the realization that our time here is finite. I fell in love with cruising when i had the good fortune to work for Princess as a musician in the mid-70's. And my father passed before he was able to fully enjoy the fruits of his labor; so I have been indulging my passion--within reason of course--ever since.
As I suggested to another poster in the Princess forum, you can click on the "Find" tab at the top of thie page and enter the names of your ports. You will get much good information, including excursion suggestions. It sounds like you already know what you want to do; you just have to figure out which to do where.
