Hello. The best months to go to Danang are March, April, early May and September. December, January and February are wintertime, so the weather is usually cloudy, windy and rainy. And the sea has a grey colour in these months. *Banh mi* and *banh xeo* are popular foods here. They are delicious and not expensive.
About tip: US $1.00 or VND $20.000 Yen $100 is very much appreciate! Depend on hotel you will have free spa session or fee , this resort has included free spa into room selection. Bon voyage!
