2) When a Sim serves a group meal, you can click on the serving platter to call the whole family to eat.
Have you actually gotten that to work? When I tried, the guests just went about their business sitting in the hot tub or playing kicky bag etc.
Doesn't work for me at all. Tried it with Nina Caliente. Everyone just kept doing what they were doing. No one came to the table.
An aside... be careful of the initial invites downtown. You never know who's going to show up in the group. Nina received my first call to go downtown from Don Lothario. I had her accept because it was the first time I had a sim go downtown. Well, 7 sims in total were in the cab when it arrived at the restaurant - Don, Nina,
Dina,
Cassandra, Angela and Lilith Pleasant, and Alexander Goth. All Maxis created Sims that I've played. It was a disaster! Nina kissed Don immediately upon exiting the cab, which made Dina furious. Also, Cassandra and Dina have the Don in common. Cassandra followed Dina around the lot all evening slapping her. Nothing stopped it! And unfortunately, it's all saved. Now Dina keeps stopping by Nina's house and kicking over the trash or stealing her newspaper! I have so much relationship clean up to do...
