Ok, it’s a huge cruise ship in a warehouse, that doesn’t move. You pay to stay on it and you’ll have the whole cruise experience without the moving around or being on the sea. There would be light projections to simulate night and day, and also it would be warm.
I guess my market would be people who can’t afford a cruise and/or aren’t that bothered by the destinations side. My grandparents who have been on lots of cruises say some people don’t bother to get off to see Rome or wherever.
I was thinking about those Disney cruises where the selling point is the cruise itself and the activities/ water park.
It would also be a safe bet due to being in a controlled environment. Wouldn’t be disrupted by wars or weather conditions.
I think I was inspired by the huge ship they built for the film Titanic.
