A bilingual site sounds simple — write everything twice. Done well, it's more thoughtful than that: some things every guest needs in their own language, some are better left as they are, and a few should never go through a machine.
Translate what a guest acts on
The parts a guest reads to make a decision or avoid a mistake should be clear in both Thai and English: room names and descriptions, prices and what's included, the booking and cancellation policy, directions, and how to reach you. If a guest could book the wrong thing or arrive confused, that text earns a proper translation.
Leave what's better untouched
Some things don't need translating — and look odd when they are. Your property's name, a Thai dish on the breakfast list, a place name, a well-known local festival. Guests usually prefer these in the original; a forced translation can read as trying too hard, or lose the meaning entirely.
Don't let a machine write your welcome
Machine translation is fine for a rough draft, but not for the lines that carry your voice — the welcome, the story of the place, the careful wording of a policy. Those are where calque and small errors quietly cost trust. A native pass on the copy that matters is worth far more than translating every last word.
Keep the two languages in step
When you change a price or a policy in one language, change it in the other the same day. A site where the Thai says one thing and the English another is worse than a one-language site — it tells a guest you're not paying attention. One small habit keeps both honest.
Good bilingual isn't twice the words — it's the right words, in the right language, kept in step. If you'd like, we can build your site so Thai and English guests both feel it was written for them. We're on LINE.
