First of all "I've had an idea to do a cruise ship game for a couple of months now, ever since we had to postpone a vacation due to 2020's global pandemic." This sucks. I had to cancel a vacation too. Hope you get to go as soon as possible!
I haven't seen other hours yet, but I love the idea! Completely on par with real cruises (from what I've heard, never been on one yet :D ) I'm excited to see other locations!
