Plan a Birthday Morning Treasure Hunt Around the House for Your Partner

I want to plan a fun, personal treasure hunt around our home for my partner's birthday morning. They'll wake up, find the first clue, and follow the trail until they reach a final surprise.

Here are the details:

- Partner's name: [Name]
- Their personality / sense of humour: [E.g. loves a riddle, gently cynical, soft and sentimental, not a morning person]
- How long we've been together: [Time together]
- A few in-jokes, nicknames, or shared memories I'd like woven in: [List 3–5]
- Rooms or areas in our home I can use: [E.g. kitchen, living room, bathroom, bedroom, hallway, garden, car]
- The final surprise waiting at the end: [E.g. their favourite breakfast cooked and ready, a wrapped present, tickets to something, a handwritten letter]
- How many clues I'd like (between 5 and 10): [Number]
- Tone of the clues: [E.g. cheeky, sweet, riddle-style, sentimental, silly]
- Anything to avoid: [E.g. food allergies, sensitive topics, places they wouldn't go, pets that knock things over]

Please give me:
1. A 'welcome' note for the very first clue that sets the scene and gently explains how the hunt works.
2. A full set of clues that lead from one location to the next. Each clue should feel personal to us — drawing on the in-jokes, memories, and nicknames I've shared — not generic riddles you'd find online.
3. A short list of practical setup tips: what to do the night before, what to write each clue on, where to tuck it, and how to stage the final reveal so it lands.
4. A 'plan B' for any clue that might get knocked over by a pet, moved by a housemate, or spotted too early.

Keep the language warm and natural — never cringey or overly poetic. Use British English.
