The Total: $1,187 USD for 21 Days in Vietnam, Cambodia, and Thailand

This includes flights from Atlanta. I want to be precise because budget travel writing that does not include flights is budget travel writing for people who already live in Southeast Asia. If you are starting from the US, here is every number and every decision that got me to under $1,200 for three weeks in three countries.

The Budget Breakdown

How the Flights Were $487

Google Flights matrix search, flexible on departure day by ±3 days, flying into Hanoi and out of Bangkok (open-jaw routing, always check this — it is frequently cheaper than returning to your origin city). Booked eleven weeks in advance. The sweet spot for Southeast Asia flight prices from the US East Coast is generally 6-12 weeks before departure. Anything under 3 weeks or over 16 weeks typically costs more.

Accommodation at $9/Night Average

Hostels, specifically: mixed dorms in Vietnam ($4-6/night), Cambodia ($6-8/night), and Thailand ($8-12/night). The specific hostels I used in Hanoi (Vietnam Backpacker Hostels), Hoi An (Tribee Hoi An), Siem Reap (Mad Monkey), and Chiang Mai (Stamps Backpackers) all had excellent ratings, strong communities, and organized social activities that were free or near-free. I am a solo traveler. Hostels are not just about the price — they are social infrastructure that makes solo travel significantly less lonely and significantly more efficient at finding people to share costs with (day tours, tuk-tuks, etc.).

Food at $8/Day in Three Countries

The key is where you eat, not what you eat. Street food in Vietnam is extraordinary. Pho at a streetside plastic-table restaurant in Hanoi: 35,000-50,000 VND ($1.40-2.00). Banh mi from the right stall: 20,000 VND (under $1). Bun cha from a spot the hostel staff recommend: 50,000 VND. I ate three meals per day, none of them compromised by cost, because the cheapest food in Vietnam is also the best food in Vietnam.

The single money-saving rule: eat where motorcycles are parked outside and there are no English-language signs. This fails approximately once per trip. The success rate otherwise is above ninety percent.

The Safety Note for Budget Black Women Travelers

Solo Black women traveling budget in Southeast Asia are sometimes told it is unsafe. My experience: Vietnam, Cambodia, and northern Thailand are genuinely very safe for solo women. The specific safety measures I used: staying in social hostels with 24-hour front desks, taking registered taxis or Grab (Southeast Asia Uber) rather than unmarked vehicles, and keeping digital copies of all documents. I did not experience any racially motivated incidents. Occasional staring, particularly in less-touristed areas, but no hostility.
