What's the latest on doing a visa run to Luang Probang, can you enter Laos there and get a Lao visa on arrival? If so what is the visa cost? I did it to Vientiane years ago, but at that time you couldn't enter LP without a visa.
TLDR : Answer Summary
You can obtain a visa on arrival (VoA) when entering Laos at Luang Prabang, which costs USD $40 or 2,000 Thai Baht. Ensure you have clean U.S. Dollar banknotes and two passport photos. Travelers have reported varying lengths of stay on their Thai visas, depending on nationality, and entry to Laos can typically be accomplished directly at the Luang Prabang airport.
