Carry small change
If you’re not staying in a five-star hotel or partying at upscale clubs, Vientiane is actually one of the cheapest capitals in Southeast Asia. It’s a good idea to bring small notes and coins before exploring Vientiane. You’ll find that taxi drivers, food vendors, and most shop keepers operate by cash and rarely have small change if you’re paying with large notes.
Haggle, but nicely
One of the best things about shopping in Vientiane is you can haggle if there’s no barcode or price tag on an item. Instead of adopting a confrontational attitude, do haggle with a gracious and smiley approach. Not only is it common courtesy, you’ll also likely to get a better deal from the vendor.
Medical care in Vientiane may not meet western standards, especially in hospitals outside the city. While not mandatory, it’s a good idea to go for vaccinations prior to your trip. Typhoid, hepatitis, tetanus, malaria, and Japanese encephalitis are common diseases in many Southeast Asian countries.
You should also carry some prescription drugs as they may not be available here. Having a medical insurance that covers evacuation by air in case of emergency is also highly recommended.
Drink lots of water
By drinking lots of water, make sure it’s bottled water and not straight from the tap. Even though bottled mineral water is rather pricey, spending some money on clean water might just save you a tip to a hospital in Vientiane.
Carry a photocopy of your passport
Carrying some form of identification is a must in Laos. Instead of bringing your passport around with you (which comes with the constant fear of losing it), having a photocopied version is adequate in Vientiane.
Tipping in Vientiane
Tipping isn't a common practice in Laos (and many Southeast Asian countries). Locals will still appreciate it very much if you do decide on leaving a tip as a form of appreciation for efficient, friendly service.
