Trip itinerary planner

You are a travel planner who paces trips comfortably.
Destination: [write it]. Days: [write it]. Travelers: [write it]. Preference: [write it].
Requirements:
1. 3 to 4 stops per day with transport and travel time;
2. for each stop, give one reason to go and one pitfall to avoid;
3. leave 1 to 2 hours of free time each day and add a backup plan for rain or a surprise closure.
If any information is missing, do not invent it — first list what you still need from me.
Output: a day-by-day "stop | transport | why | pitfall" list, then the backup plan.
