1. Visa -- It is better and convenient way for you to get visa through travel agent like Hanoi Package Tours or if you want to pre-arrange a visa on arrival online , you run the risk of waiting up to 90 minutes in Hanoi airport while the visa officers decide whose turn it is to do some work.
2. Transportation – for safely and save money, before you go to Hanoi , should book from travel agent or hotel you reserve, the second choice you can arrange your self which is cheaper, a ride into town from Noi Bai airport costs around VND 400,000 (US$ 20) with 4 seat car if you talk about price to driver before getting in the car, or you want to see meter sometime driver will take you around before get to the point and charge more than that.
3. Communication – if you wonder around Hanoi Old Quarter , almost locals speak a few phrases of English but anyway without tour guide you should try to learn some Vietnamese phrases or writing on paper, because it’s quite difficult for travller can pronunciate Vietnamese correct language with six different tone.

5. Currency -- There are around 20,000 Vietnamese dong to one U.S. dollar, so don’t freak out when the bar tab comes along. U.S. dollars are also widely accepted in tourist area.
6. Climate -- An intolerable mix of heat and humidity in the summer (June-August) reaching 40 C, a pleasant shower-splashed spring (March-May), a gorgeous walking-in-the-park-every-day fall (September-November) and a cold yet humid winter (December-February).
7. Vaccinations -- Tourist are always advised to get themselves protected against the most common diseases, including: Hepatitis B, tetanus-diphtheria and typhoid. Also wise to take anti-malarials if you’re spending long periods outside the major urban areas or traveling in the hot and humid months.
8. Eating -- You can’t come to Hanoi and not eat pho ga (chicken noodle soup) but when you come to Pho 24 Noodle you will have different taste aand you will remember that.

9. Drinking – Bar or night club you can find out everywhere but you should not try it too late, sometime you can Hanoi local beer it is good or local wine from the people you know but if not you should not drink so much, other drink you should try as Coffee and Tea which are good for traveller.
10. Shopping -- Hanoi’s old Quarter is lined with various fashion stores, souvenir stalls, snack and trinket sellers but almost come from China or like copy one, so you buy for your self and want to use it for long time you should buy in Humanity center, first good one , second good for disable people but very expensive. if you’re looking for an air-conditioned mall experience head for the Vincom City Towers where you’ll find luxury brands, a cinema and a colorful gaming area. Vincom City Towers, 191 Ba Trieu St., Hai Ba Trung.
11. Traffic -- When Hanoi people move they tend to do it on scooters. And if you wait for a break in the flow of scooters when trying to cross the road, you may miss your flight home. Walk out with intent and slowly, and they will avoid you. We promise.
