Just for your information, given that you are offering advice to people. There is no such thing as an IDL, (International Driving Licence). it’s a called an IDP (International Driving Permit). And legally is only valid if you also produce your country of origin driving licence.
My pleasure, don’t get involved in all these complicated machinations with people who have no idea what they are talking about and just confuse the issue. Rock up, get your 60 day visa free entry and if you want to stay longer, wander along to your nearest immigration office, pay 1900 baht and they will extend it for a further 30 days. Simples.
