If you ran a cruise line, what new entertainment would you actually add?

With Royal rolling out Icon and Star and NCL putting slidecoasters on ships, it kind of feels like we’ve hit peak theme park at sea.

So if budget and engineering limits magically didn’t matter, what would you actually want to see added to a ship?

For me, it’d be a massive lazy river that wraps all the way around the top deck. I know water weight and ship motion make it a nightmare, but just imagine floating around the perimeter with a drink, ocean on all sides, zero rush.

Curious what ideas people have that aren’t just “bigger waterslide.”
