Ideas
I created a custom venue getaway for a ski resort, and had eat breakfast scheduled along with self care and bathe before the sims go off to do snow activities. I liked that at 9am all the sims went off to ski and snowboard including my own sims, I might actually go to the snow world more often as it was lively with sims doing activities for once.
I did not like that before that at 6am my sims that were not hungry - they had green food bars kept cancelling out my instructions to bathe which was yellow so they could eat. Even though eat was an activity it wasn't the only activity that could be done during this period of time.
I also noticed that the NPCs would eat one plate of food and immediately go and get another plate to begin eating. My sims did the same lining up multiple eat food in their queue's which I had to cancel out. I was very glad when the 3 hour window for self care/breakfast was over and it ticked over to the snow activities.
I'm not sure if I will keep eat as an action item in the future with how overpowered it worked if there is no balance to them eating based on their need bars and it's just lined up because that is the activity scheduled to do during that period of time regardless of if the sim is hungry or not.
