Act as an experienced travel planner. I want a complete, day-by-day itinerary for a trip to destination, lasting number of days days, for number of people traveler(s), with a total budget of amount and a budget / comfort / luxury travel style. My interests are food, history, nature, nightlife, shopping, etc.. Follow these steps: 1) Build the itinerary split by day, with morning, afternoon and evening suggestions. 2) For each activity, add an estimated average cost, travel time, and the best time of day to avoid crowds. 3) Suggest where to eat near each spot, with a price range. 4) Include local transport tips and ways to save money. Present the result as a table per day and, at the end, show an estimated budget summary by category (lodging, food, transport, activities). Consider the time of year and flag anything I should book well in advance.
