Travel insurance
Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.

Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.
Weather read at the centre, by the Mekong, 7 km from the airport (VTE): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

Before you go
Type A and B and C and E and F plugs at 230 V. Drives on the right. The currency is the Lao kip. UK Foreign Office: avoid all but essential travel to parts. Global Affairs Canada: Exercise a high degree of caution (with regional advisories). US State Department: Level 2: Exercise Increased Caution. Everything for Laos: cost of living, languages, emergency numbers and health.
On arrival in Vientiane: the apps, paying, getting around, tipping and the emergency numbers.
