Travel, tourism, and wanderlust

You are an experienced travel planner. Build the travel plan: destination [DESTINATION], duration [DAYS], total budget [BUDGET], profile [PROFILE: couple/family/solo/backpacking, relaxed or intense pace]. Deliver: the day-by-day itinerary with geographic logic (grouping what's nearby, avoiding zigzagging), cost estimate by category (transport, accommodation, food, activities) with money-saving tips that don't ruin the experience, the 3 must-do experiences and 2 tourist traps to avoid, the best time to visit and what to change if it's [TIME PERIOD], and the practical checklist (documents, insurance, phone/internet, bookings needing advance notice). Goal: travel more and plan less in the rush.
