What would be your VISA recommendation for visiting Thailand for a period 6 months. During that time we plan to be based in Hua Hin but also travel around other parts of Thailand and likely a couple of weeks in Vietnam & Malayasia. (so border runs may already be "built-in" to our schedule).
TLDR : Answer Summary
For a 6-month stay in Thailand with travel plans in and out of the country, a Multiple Entry Tourist Visa is recommended. This visa is valid for 6 months and grants 60 days of stay per entry, with the option to extend for an additional 30 days. Travelers can plan border runs to maximize their time in Thailand, potentially allowing for nearly 9 months of stay if managed correctly.
