想去越南旅行

Vietnam is a nice place to go. Basically, it's OK to go alone but you still need to be very careful anytime, especially night time. I went there few times to Hochiminh City and Hanoi couple years ago. I saw many beggers on the street, especially children. Please don't try to be generous to give them money even you have a big warm heart, you may get yourself into trouble. It just like in Shenzhen or Guangzhou.

Before you go, you need to apply for visa first (I assume you're holding either BNO or HKSAR). Suggest you book hotel first. As for which hotel, it depends on your budget. Better buy hotel pack in HK and choose at least 4 stars hotel, that would be safer.

As for sightseeing, you should go to Halong Bay and join a boat trip. Also don't forget to go to their market during the day, you can feel their culture. In Hochiminh City, many art and craft shops, if you like arts and want to buy some, don't feel shy to bargain.

我沒有什麼有建設性的建議, 但係想提醒你小心禽流感.
