I can tell you, i'am from denmark, the last many many years, i got a SETV from Denmark, got a 30 days extension on the lokal immigration in Patong, have a fligth for a new SETV in Penang, and again 30 days extension,after a short flight to Singapore or Kuala lumpur and back the same the date,again 30 days and new extension on Patong immigration, so i can stay here for almost 7,5 month, and nobody ask for any money,just be aware the Immigration in Penang have chance to new bad rules,so if you want go a new SETV go to Kuala lumpur if need
Yes, a SETV is the best option for you,its 60 days,after that a extension on a immigration for 30 days more (1900 bht,) and then make a cheap flight out of Thailand,and you wil get 30 days and again you make a extension for 30 days more
No, it's still easy, you just need a ticket out of Thailand, but they now have a limit of 200 applications a day, so use a visa agent, it only costs small money.
