I've booked a 90 day return flight and a 90 day accommodation stay with a 60 day visa. No problem just tell the place you are staying (only if they question you on your passport date stamp) that you will be applying for a 30 day extention because they have to vouch for you on an immigration form (T30). But they can maybephone the hotel/owner where you're staying. Don't worry just do it. Or if you are concerned get a flexible flight ticket.
Western Union or cash but if you have to use and ATM, 220 baht charge every ATM. Krungsri probably best rate and amount (depending on your banks max daily withdrawal amount).
Mr Vee Melvin it's like Wikipedia don't believe or take it all too seriously. Look at the good advice and those that care and dismiss the rest good luck matey. 👍 An x veteran myself.
I understand what you are saying the TR-METV gives you the security and reduces the risk with Customs. Puts your mind at rest, especially when visiting a few times every year, l agree. Some people answer but do not always understand themselves.
