Tartosa residential Beach lot - what to do there?

I made it into a residential. However, it's logical in my game. This is the first world since Sulani, where Mermaids even come close to being usable. So, for me, Tartosa is a mermaid world, not a wedding world. I am not all that interested in the wedding venues and the weddings gameplay, I got the pack for the build/buy, and the beautiful new world.
