Stay practical near your schedule

- Front desk routing tips by time of day can help you avoid avoidable delays.
Common mistakes (and how to avoid them)
- Skipping short-term checks (weather/opening hours/schedules) → verify before you head out.
- Overpacking your schedule and crossing the city repeatedly → cluster locations and add 20–40 minutes buffer.
- Carrying too much cash/documents → carry only what you need and keep copies/photos.
- Not confirming prices/units/fees → ask first, especially for add-ons.
- Not pinning key addresses → pin your hotel and 2–3 landmarks.
A simple one-day structure (template)
- Morning: your main task/attraction (start early).
- Midday: light meal + 30–60 minute rest (useful in hot weather).
- Afternoon: flexible items within one cluster to reduce detours.
- Evening: dine near your base; keep nights lighter for safety.
Practical transport notes for Hanoi
Traffic can change quickly by time of day. Avoid cross-city detours during peak windows, keep pickup points clear (main gate/lobby), and add buffer time in rain.
- Use area clusters: central (lake/Old Quarter) vs west corridor (Cau Giay – My Dinh – Keangnam).
- Walk inside compact central areas; ride-hailing for longer legs.
- For multi-stop days, an hourly car can reduce waiting time.
