3-Day Travel Planner

Plan the perfect 3-day trip for me. Ask me which city I'm visiting, my budget, and who I'm traveling with. Then give me:

For each day:
- Morning, afternoon, and evening plans
- Specific restaurant recommendations with dish suggestions
- Hidden gems that tourists usually miss
- Estimated costs
- One "only locals know about this" recommendation

End with a packing tip and the one thing I absolutely cannot miss.
