Best bases
These are the base choices that should replace generic one-size-fits-all city copy.
Best bases
| Area | Best for | Watch outs | Transport logic | Walkability or spread | Caveat |
| Old Town / riverfront | food, culture, walking | rain/flood caveat | walk/road | compact | river/rain |
|---|
| Gem Market / Si Chan Road | gem/jewelry vertical | needs buyer due diligence | walk/road | compact | rain |
|---|
| Chao Lao / Laem Sing coast | beach add-on | away from city/gems | road | spread | coastal rain |
Season windows
Use static season framing to narrow the trip shape, then let daily weather, AQI, ferries, and events stay live.
Season windows
| Window | Guidance |
| Best | November–February |
|---|
| Acceptable with caveats | March–May heat, May–October rain-aware travel |
|---|
| High risk | gem/gold pricing and shop trust cannot be static |
