Just to give an update about getting visa in Vientiane. It was super easy. I gave them just 3 papers, flight booking, accommodation booking and bank statement. Visa is 1000 baht. I finished everything both times in less than 10 minutes. Can't remember when I got any visa easier. Vientiane is a small and walkable city. First time I walked to the embassy, second time I took a motor taxi which costed me 1.30$. There were few people applying for visa since everyone else got 45 days visa free exemption.

I heard the same for Cambodian border, especially the one from Siem Reap to Bangkok that it's very strict and sometimes might refuse visitors.

Thank you for the advice. This looks a bit like a hassle. I guess it's better to pay some extra money and fly from Chiang Mai. The reason I want to go to Luang Prabang first is because that way I can travel by land to Vang Vieng, Vientiane and then enter Thailand and go by land to Bangkok without thinking about flights. If I do Vientiane first, which in this case is easier option than Luang Prabang, I have to know when I will fly from Luang Prabang and by ticket upfront. First option is a bit more relaxing.

Thank you so much for the advice. Yes, I already have bank statement ready, will book accommodation for the first few nights and a bus ticket. I heard that I also need an airplane ticket leaving Thailand.

As from the info I found online, they only ask to have booked first night in a hostel. Thailand was never strict with documents for visa, but I always give them more than they ask just in case.

I managed to book easily an appointment for 24th. Strict in what term? Having all documents usually helps. If they don't give me visa, there are plenty of other countries to visit, I am not worried too much, but it would be nice to be able to come back to Thailand for another 2-3 months.

Thank you for an advice. I will check about an appointment now. As far as I remember, I've never had any problems to get Thai visa and I got 4 so far.
