The first day I would build
Let one coastal anchor carry the day.
- Use Liugong Island when the weather gives you a clear outdoor window.
- Keep Weigao Plaza as the central reset for food, shopping, or a weather break.
- Do not scatter the day across inland errands and seafront walking.
If the forecast is kind, I would build the first real day around Liugong Island or a seafront route. That gives Weihai its identity quickly: water, wind, distance, and a cleaner coastal pace than many larger Chinese cities.
After the outdoor block, move toward a practical center rather than forcing another big sight. Weigao Plaza is useful because it gives the day a clear address, food, shops, and an easy place to regroup.
