It seems that everyone is busy with their respective plans and meetings. Here's an updated schedule:

Name: Peter 2025-12-03 10:00 @ Caroline's Café: AI project discussion with Caroline

Name: Andy 2025-12-03 13:00 @ Park: Quadruple date and AI project discussions with Samantha, Diego, and possibly others under the oak tree.

Name: Diego 2025-12-03 14:00 @ Café: Discussion about zine club plans with Noor at 2 PM sharp instead of 7 PM. They'll also feed stray cats during their meeting on Thursday, 3 PM sharp.

Name: Samantha 2025-12-03 14:00 @ Museum: AI project discussions with Andy and possibly others under the oak tree.

Name: Noor 2025-12-03 15:00 @ Theater: Discussion about community garden, zine club, and feeding stray cats with Samantha on Thursday, 3 PM sharp.

Regarding your initial question about inviting Caroline for a quadruple date, it appears she already has an AI project discussion scheduled for the same day at 10 AM. So it might be best to plan another time that fits everyone's schedules.
