I like the following if my sims have free time.
- do something creative at the house like playing a musical instrument (mostly violin) painting, knitting or cross-stitching
- if it is just a few hours I have them play on a gaming console on TV or a board game like don't wake the llama. I like that both of these can be done by multiple sims together
- go to the beach for a day (sulani or tartosa)
- go hiking in Mt Komorebi
- go sledding or skiing if it suits the season
- visit a festival in San mychuno or Mt Komorebi if one is happening. Some are during the week but still fun if it happens to be a day off at work
- go bowling
- have dinner at a restaurant
- visit a spa
- do some yoga or exercise at the gym to loose a few pounds
- have a club gathering. I created a group of friends to easily gather people to hang out with
