Should I bring cash or use ATMs?

Bring a debit card with no international transaction fees. ATMs are plentiful, but watch for high withdrawal fees; withdraw the maximum amount to minimize charges.

Is it safe to drink the tap water?

No. Only drink bottled or filtered water. Even for brushing your teeth, it is safer to use bottled water.

How to Spend Two Weeks in Southeast Asia

Focus your two weeks on two countries to avoid spending all your time in transit. Prioritize Vietnam and Thailand for a mix of urban culture, street food, and nature without burning out on travel logistics.

Pick a regional pair. Don't try to see four countries. Pair Thailand with Cambodia, or Vietnam with Laos. This limits your flight time to 90-minute hops.
Book your regional flight early. Use low-cost carriers like AirAsia or VietJet. Book these at least 3 weeks in advance to keep costs under $80 per flight.
Handle your visas in advance. Vietnam requires an E-visa for many nationalities (apply 7 days prior). Thailand offers visa exemptions for many, but check the official immigration portal before booking.
Get a local SIM card at the airport. Walk to the official kiosks in the arrivals hall. Expect to pay $10–$15 for 15GB of data. Do not use your home carrier’s roaming plan.
