You've been presented with a few options another is if you're over 50 buy a 90 day non-o based on being over 50, by showing you have 800,000 baht equivalent $35,000cdn each in the bank. Then you can bounce out to another country and enter on the free Visa exempt stamp for the last part of your holiday. That way you're not doing back-to-back Visa exempts, no risk on entry, and you also wouldn't have to show the airlines a return ticket.
Can we please stop beating this to death. If the transfer is showing up with a weird coding you have a couple of choices you can get the FET, or simply prove the transfer from your international Bank to the local bank the same amount the same day the same time, most immigration officers will accept that the money came from abroad if you can supply a paper trail.
You'll get a 60-day free visit exempt stamp every time you enter. 72 hours or less before each arrival you go online and fill out your free tdac arrival form.
What entry scheme do you plan on using,soft power or digital nomad? Do not do an in country extension. Just border bounce or fly to a nearby country for an hour, day, or week. An in country extension will require all updated original paperwork requirements plus plus. Just don't.
