Is it possible to stay in Thailand for 90 days using visa-free entry and extensions?

You could extend the first 30 days. Then go out and back in ... and if you want extend the second 30 days.

You could, but why not get a tourist visa? It saves you the hassle of flying out and in.

Sir. Anytime now you’ll get a 60 day on arrival, then you can hit up immigration for the 30 day. 90 total. No exit and reentry needed. We’re just waiting patiently.

When going to Thailand for 31 - 60 ( 90 )days, the 60 days touristvisa is the best option.

It is cheaper than visa excempt + 30 days extension.

No need of a onward ticket ( 90 days 1 onward ), if returnticket within 60 days.

It is easier to apply from the comfort of your home.

If visiting the nearest Thai Embassy website, you may find informations, that make it much easier to apply online.

Not wasting holiday time to find, go to and waiting at a immigration office ( 90 you would need that ).

Then no need to leave Thailand in up to 90 days.

If you don’t have any previous history of travelling in and out of Thailand, you should have no issues with doing two arrivals on visa exemption and stay for 90 days in total.
