What is the easiest and most cost-effective way to apply for a 60-day tourist visa in Thailand?

The conversation revolves around an expat's experience with visa regulations in Thailand, discussing the potential challenges of relying on visa exemptions and the need for a proper 60-day tourist visa. The expat inquired about the most economical and straightforward methods to acquire this visa, considering a train journey to Laos. Responses suggest that while applying for a 60-day visa is generally advisable, it does not guarantee entry, and past immigration patterns could affect re-entry. Several commenters recommend Savannakhet in Laos as a favorable option for obtaining a visa without an appointment, also cautioning against overly frequent border runs. Some suggest exploring alternatives like the Elite or Long-Term Resident (LTR) visas for longer stays.
