Guys, let me just remind you all that it would be nice if you would actually read my post and if it's not too much, respond kindly as well. There is no need for treating me as if I'm stupid after i got into a medical emergency the day before my visa expired, after which I was hardly able to walk and I was just following my doctor's advice on my visa (which I'll never do again) . Honestly, it won't kill you to be kind.
For Vientiane there are 4 options as far as I know:
1. Local bus. Check chiang mai buddy's page on visarun to vientiane on their website. You have to figure everything out yourself, but it's not difficult and the cheapest option.
2. Aya visarun services. This company is all by bus too, but basically holds your hand throughout the entire process. However, the bus is not as comfortable and its a bit more expensive.
3. By plane, obviously the most comfortable option, but a lot, a lot, a lot more expensive
4. Nok air fly and ride. Flies you to the border of Thailand, which is a lot cheaper because you don't have to pay the country taxes and takes you by bus afterwards.
I haven't been to other embassies, but I know Vientiane is the best for Thailand, especially if you're not going for a tourist visa. Good luck! 😘
