Can I spend the night at Ho Chi Minh Airport?

Only the terminal can sit.

Besides, it may be more dangerous for you two girls to spend the night at the airport than to take a taxi to find a hotel.

Find a more regular taxi. You can also find a hotel online in advance and take a taxi to tell the driver where you are going. If you tell the driver which street the hotel is on. They won't lie to you. Because they will think that you are familiar with that place.

I am in Hanoi. You can call me if you need help. 0 168738 1629
