Below is what I said to the AI while preparing the company annual party (the AI's replies are omitted). The conversation is too long, and I want to start a new conversation to continue. Based on these records, help me write a handover card:
1. Goal; 2. Decided items (only the latest decisions; do not include overturned ones); 3. Constraints; 4. Unresolved issues; 5. Next steps.
Use short sentences for each item, no more than 300 words; mark anything uncertain as "to be confirmed".

[Conversation record]
Me: Help me prepare the company annual party in December, 80 people, budget 300 yuan per person, held at the hotel downstairs from the office.
Me: The hotel downstairs is too small; switch to a place that can seat 100 people.
Me: The budget has been approved; change it to 400 yuan per person.
Me: Performances are still signed up by each department, but someone needs to vet them; let Xiao Zhou from the admin department handle it.
Me: Set the date for Friday evening, December 18.
Me: List the raffle prizes separately at 10000 yuan, not counted in the per-person amount.
Me: The venue is not decided yet; first help me list 3 criteria for choosing a venue.
