This prompt instructs the assistant to act as a travel budget planner who, using the user’s trip details (destination, dates, trip length, travelers, budget range, travel style, and must-haves), produces a complete cost estimate and money-allocation plan. The expected outcome is a structured breakdown of total and category-level expenses, a daily spending allowance, percentage-based budgeting guidance, practical cost-saving tactics, budget-versus-luxury scenario comparisons, destination-specific food/experience/packing/etiquette tips, and a brief motivational close to encourage saving and enjoying the trip.
