Is it cheaper to travel as a couple or solo?

As a couple. You split the cost of a private room, which is often cheaper than two beds in a high-end hostel dormitory.

Should I bring cash or cards?

Bring a debit card that refunds international ATM fees (like Charles Schwab). Cash is king in Southeast Asia; always keep $200 USD in small bills as a backup.

Planning a Budget-Friendly Couples Trip Through Southeast Asia

Stick to the 'Banana Pancake Trail' countries like Thailand, Vietnam, and Laos to keep costs low. Book your regional flights at least 6 weeks in advance and prioritize guesthouses over hotels to keep your daily spend under $70 for two.

Map your route by proximity. Don't fly across the region. Start in Bangkok, move north through Laos, head down through Vietnam, and finish in Cambodia. This allows you to use cheap sleeper buses and trains rather than expensive regional flights.
Set a non-negotiable daily budget. Set a target of $70 per day for the couple. This covers one private room ($25), food ($30), and activities/transport ($15). Use a shared app like Splitwise to track every cent.
Use local transport hubs. Use 12Go.asia to compare bus, train, and ferry prices. Never book transport through your hostel; walk to the bus station or use the official app to avoid a 20-30% markup.
Balance your itinerary. Mix 'expensive' days (guided tours, diving) with 'cheap' days (walking tours, beach time, local markets) to ensure you don't burn through your budget in the first two weeks.
