A couples' trip to Bangkok works best when the river does the sorting. Base on the Chao Phraya and the city arranges itself into two moods — the unhurried riverside evenings, and the charge of the modern city a short boat or car ride away — so the days never collapse into a single exhausting itinerary.
We set the base on the river first, hold the two dinners worth dressing for — one on a rooftop, one on the water — and leave the markets, the temples, and the long lunch to find their own place in the day. The work is pacing: keeping the evenings as the fixed points and letting everything else stay optional, so the trip feels private rather than packed.
