I used to work on a cruise ship and hope this doesn’t come across as negative etc but if I were to be on a cruise as a passenger, I would spend the first half hour cleaning the room with Clorox wipes. Wipe the countertops and the phone ...wait here is a good link lol. This isn’t being a germophobe which I am not, it’s just straight basics to me. I have seen how fast the rooms get cleaned and it’s pretty eye opening...that is not to say all cruises are alike but it is a super fast turn around for cruises, there simply isn’t time to do it right.

Also
My preference is to get a room in the middle of the boat, you wouldn’t think waves would ever be an issue and almost all the cruises I was on never are, but when the waves come it can be intense and being in the middle of the boat is best as rocking can be pretty unreal at times lol
Here is a great link explaining cabin placement, not really a big deal but something to think about etc

I can talk a lot about ship life as a crew member but no need lol
