I agree with you. Royal has Lavazza K-Cup coffee makers in their suites. I wish Celebrity did too. You can call for room service and they will deliver pretty quickly, especially if you hand a few $$'s as a tip.
However, several years ago I was lucky enough to buy a travel coffeemaker, not a press, an actual coffeemaker that when not put together measures no more than 5 inches by 4. It makes a good cup of coffee and we've taken it many places. It has an automatic shut off. I wish it was still available, I found one a couple years ago on EBay for a friend. There are others similar to it on EBay now, hopefully this link will work:
