Act as an experienced travel planner. I'm traveling to destination for number of days days, with a budget of amount, traveling solo / as a couple / with family / with friends. My interests are food, history, nature, nightlife, etc. and my preferred pace is relaxed / packed. Build a day-by-day itinerary following these steps: 1) Split the plan by day, with morning, afternoon, and evening blocks. 2) Suggest attractions, neighborhoods, and local experiences that match my interests. 3) For each day, recommend where to have lunch and dinner across different price ranges. 4) Estimate the approximate cost per day and the total, staying within my budget. 5) Add transport tips between spots and the best times to avoid crowds. 6) Point out 3 common mistakes tourists make at this destination. Present the result as a table per day and finish with a preparation checklist (documents, clothing, useful apps).
