Plan a long weekend itinerary that isn't just Saturday panic

Plan a long weekend itinerary.

Destination: [details]
Leave / return times roughly: [details]
Who: [details]
Priorities: [list]
Travel mode: [train / car / flight]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. Fri–Mon outline with travel buffers.
2. One anchor activity per day.
3. What to pre-book vs freestyle.
4. A shared checklist of bags and tickets.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, prices, opening hours or bookings. UK English.
