£150 for METV IN ENGLAND

You need an METV.

METV...

The safest is to get the METV - can come and go as often as you want within the 120 days, but you will need to show your exit and reentry plans for first entrance and maybe second entrance.

yes the METV will cost a little more, but saves you the time and trouble to get extension and any issue with entering a second time.

If you go with other plan, you could either extend the 60 by 30 or the 30 by 30. I might consider extending the 60 unless you have reason to leave after the 60 instead of after 90. I can see a lot more issues with the second entry if for more than 30 days (having the flight out after 30 days may help get in).

Don’t you have to fly to native country as opposed to a “neighbouring country “?

Do it right like all the wet wipes on here do !

That's exactly the behavior the changes to the visa exemption program is trying to put a stop to. Stop being a cheap Charlie and get a proper METV visa.

You booked for 120 days ?? The exemption was only for 60 so you should have a visa anyway

That will work if you've no other recent history in Thailand but if you have the visa exempt might be an issue. The Multiple Entry Tourist Visa (METV) would be a better option

apply for a 90 day visa

Or get yourself a METV multi entry tourist visa. That is a 6 month visa. But you can only stay in the country for 60 days straight. So visit a neighbor country for a weekend and come back to Thailand.
