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 |
| Nong Khai transport core | route stop and transfer resilience | limited hotel-area depth | rail/road/bus or airport depending city | compact core plus spread route targets | heat/rain/schedule conditions can weaken route value |
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 | border/rail schedules and Naga event crowds are live |
Source candidates
These sources back the packet even when they are not all wired into live observations yet.
Source candidates
| Source | Type | Why it matters | Supports |
| TAT Nong Khai | official | official border/Mekong/Naga identity | static copy |
|---|
| Thailand.go.th Naga Fireball event | official | event/crowd signal candidate | future signal |
