How do you stay and play with The Sims?

When the Spring Sale popped up just as my kid was getting through her first week of school from home, I got us both Island Living as a rewards for surviving ;) Since then, we've both been coming up with ideas for challenges we can do at the same time. Right now, we're each working on a cat cafe, because what better way is there to relax than with furry friends and a cuppa?
