What changes should be made to island living to make it better

The little stuff would be add Rental lots. even without a complete hotel system the ability to add rental lots would make it something I would use in every save. Have At least 2 sims be able to use the boat together, ideally. Fix the food so it’s not just stuff we already have with new name(coconut cake) let us make all the new foods(poke bowl)

The big stuff is expand on the sulani culture. I felt like it was kinda there but wasn’t deep. More water activities. Add a mermaid cave, urns, bassinet.
