Tell me which city, region, or countries you want an itinerary for so I can plan route and logistics. I’ll use that to check opening hours, transit, and proximity of sights.
Give exact arrival and departure dates (and approximate arrival/departure times) plus total number of days so I can produce a day-by-day plan aligned to your schedule.
List your top interests (food, museums, hikes, architecture, shopping, family-friendly, nightlife) and whether you prefer relaxed or busy days to tailor recommendations.
Tell me approximate daily budget range and any mobility constraints (walking limits, stroller, wheelchair) so I can choose appropriate attractions and transport options.
If you have a base (neighborhood or hotel), give it to me — this helps make meal and activity timings realistic and reduces travel time in the schedule.
