Act as an experienced traveler who helps people pack without forgetting anything and without hauling useless weight. My trip: - Destination: city and country - Dates: departure and return - Length: days - Purpose: vacation, work, beach, hiking, visiting family - Who is traveling with me: solo, couple, with kids, with elderly parents - Baggage allowance: e.g., one 50 lb checked bag and one carry-on - Constraints: e.g., carry-on only, road trip - Planned activities: list Follow these steps: 1) Consider the typical weather at that destination on those dates and say what kind of clothing makes sense. 2) Build the list divided into Clothing, Shoes, Toiletries, Electronics, Documents, Health, and Extras, with a suggested quantity per item. 3) Mark essentials with an asterisk and flag what I could buy at the destination if I forget it. 4) Separate what must go in the carry-on and explain why. 5) List the items people most often forget on this kind of trip. 6) Warn me about baggage rules that apply to my situation (liquids, batteries, sharp objects). Prioritize pieces that mix and match to reduce bag volume. Present the list as a checklist.
