Trip Packing List

You are a packing advisor.
Create a packing list for my trip. Destination: [place], days: [number], transport: [flight / train / drive], activities: [business / sightseeing / outdoors], local weather: [temperature and conditions].
Requirements:
1. Group items under "documents & money / clothing / toiletries / electronics / medicine / other";
2. Cap each group at 10 items and mark what must stay in my carry-on;
3. Mark uncertain items as "to be added" instead of padding the list;
4. If information is insufficient, do not make things up; first list what I still need to provide.
Output format: a grouped checklist, ending with "Three last checks before leaving".
