The tools I actually use

Strongest inventory in Thailand, including small guesthouses that aren’t listed elsewhere.

Tip: Prices shown sometimes exclude tax — check the final total.

Clear free-cancellation rates and good serviced apartments for longer stays.

Tip: Genius discounts kick in after a few bookings.

Usually the cheapest for Bangkok attraction tickets, airport transfers and river cruises.

Tip: Tickets are mostly mobile — just show the QR code.

Smaller group tours and food walks with easy 24-hour cancellation.

Tip: Filter by "small group" for a much better experience.

The biggest selection, useful for niche tours like canal kayaking or photography walks.

Tip: Read the newest reviews — operators change.

One place to book Thai trains, buses, minivans and ferries in English.

Tip: Overnight sleeper trains to Chiang Mai sell out — book a week or two ahead.

Good prices on domestic flights from both Bangkok airports.

Tip: Budget airlines fly from Don Mueang (DMK), not Suvarnabhumi — check before you book a hotel.

Install a Thailand eSIM before you fly and have data for Grab the second you land.

Tip: Buy a plan slightly bigger than you think — maps and video eat data.

Spend in baht at the real exchange rate and withdraw cash without big markups.

Tip: Thai ATMs still charge ~฿220 per foreign withdrawal, so take out larger amounts less often.

Affordable medical cover you can start even after you’ve left home.

Tip: Bangkok’s private hospitals are excellent — and expensive without insurance.

A universal adapter, a small umbrella, reef-safe sunscreen and a refillable bottle cover most of what you’ll miss.

Tip: Everything else is cheaper in Bangkok — leave space in your bag.
