Well done Caterina.
I did know to play Clubs and Events at the same time but i don't normally play clubs so wasn't sure if it was a bug or not. Got told it likely was so didn't use it, oh well that will teach me to ask
I think i could have done better if i had done back to back, but i decided to go easy for my first challenge since i was going into surgery IRL the day after i completed it so i threw parties at roughly 6am, 2pm and 10pm everyday apart from the first day where it was 4pm and 10.30pm and the last day where it was 5.30am and 12 noon to get them in before aging at 8pm.
Like Rainbow Dash i built the party place first to complete the two Fortune Aspirations and got Observant (to avoid loner, mean and evil sims), Always Welcome (helps sims always accept your invite), Inc.Friendly (combined with Outgoing trait for insta friendship), Never Weary and Steel Bladder.
My sim was Good, Outgoing and had Dance Machine as last option so she could Disco Nap between parties.
The Lot Traits were Party Place, Gnomes and Homey (for quicker cooking and mixology skilling).
To control the playful at Dinner Party i went and dug a MySim up (good old Dr F) and spent the first few hours in a Park meeting people and making insta friends.
Part of the strategy was a befriended 1 teen (in this case Morgan Fyres) to use as my Birthday Sim for the Birthday Party and i made sure the House Party had 1 single Sim in case i needed to flirt (Thanks for volunteering Gavin Richards).
I did these two parties first to a) get them out of the way and b) have one more YA sim to party with.
I also had no elders at a party ever to avoid Grim and did Dinner Parties after the Bday and House until i completed Party Animal aspiration (used Partihaus, Roomies, Caliente and BFF for the other locations as they had a bar, stereo and sufficient dinner table space ) where i then did a few Spooky Parties. I avoided the Weenie Roast like a plague due to fire
To get people to do the "drink 3 at same time" etc i used the group function at the start of the party and disbanded group as soon as i reached gold and left the guests to get on with it whilst Daisy slept and showered and did whims/aspirations to also get Antiseptic, Stoves and Grills, Carefree and Shameless as well as say hi to any sim that walked past i did not know.
I did notice at some point that i started to be introduced to other sims via the sims i already knew- i think this was due to being level 10 charisma but not sure?
