TripPlanr detects overlapping activities and timing conflicts as you build a day, and shows a warning so you can decide what to do. It never rearranges your itinerary automatically.
- Warnings appear in the Builder while you plan.
- Activities you have marked Booked or Confirmed are treated as fixed.
- Inactive Plan B activities are not counted.
- Travel-time estimates between stops help show when a day is tighter than it looks.
