1. Best airline to fly with: AirAsia – They’re my personal favorite budget airline to fly with and fly to the most destinations. You will pay for checked luggage so make sure to purchase it when you book your ticket or you will be charged 4x the price when checking in.
  2. Buses are your best friend – Traveling by bus is the way to go in SE Asia if you want to save money. But if you’re tight on time, fly. Always splurge and go for the VIP buses. They’re never that more much and it will be a way better experience.
  3. Laos Kip is very difficult to exchange – If you’re heading to Laos you’ll have no problem getting their local currency but good luck getting rid of it when you’re out of the country. Exchange it before you leave or at the border if crossing by land.
  4. Take local transport – It’s not as bad as you’d expect, it’s cheap and it always makes for an adventure.
  5. Travel throughout the night – Yay for night buses! Vietnam has the best buses for overnight travel because they’re sleeper buses so you can actually lay down. By traveling at night you’ll save on accommodation and have more time to do things during the day!
  6. Get used to haggling – If you don’t haggle you will be over paying for everything. Some things you can’t haggle for (like food), but use your skills while at markets, shops and with transportation. Start low, you can usually tell by the look on the locals face if you’ve gone too low. And don’t be afraid to walk away, most will give in and accept your offer. If they don’t then you’re probably being unrealistic.
  7. Always go for the local beer – It’s cheap and often really good!
  8. Uber and Grab – Grab is the equivalent of Uber, but the Asian version (you can ride on the back of a scooter for cheaper than a car). I recommend these the most for the Philippines.
  9. Bring sunscreen from home – It is ridiculously expensive in SE Asia. It’s one of the few things I recommend bringing that are worth using the extra space in your bag for.
  10. Avoid package tours – Though some are great, they’re always more expensive than doing it yourself. That being said, don’t skip on all. I used tours for trekking in Myanmar, Sapa, and Halong Bay.
