I recommend allocating Day 1 for the Louvre (book ahead), Day 2 for Musée d'Orsay and Left Bank cafes, Day 3 for Montmartre and local bistros, Day 4 for Eiffel Tower and Seine walk, and Day 5 for Versailles day trip. Budget around €150-200 per person per day for mid-range accommodations, meals, and attractions. Would you like me to expand on any specific days or add more detail to the activities?",
