I’m not sure if you are aware of it, but it’s more than one city in Thailand 🇹🇭 and you can do the training in all of them.

But you can go to immigration office and pay 1900 baht for an extension.
However, you are, according to Thai law, not allowed to enter Thailand without a visa or a proof of a return ticket if you are travelling on visa exemption.
Check with any Thai authorities and then you will find out that you are wrong.
Two weeks ago I was in a meeting online with TAT (Tourist Authorities of Thailand), and was told that if you are fully vaccinated at least 14 days before arrival, then you will be allowed to enter without quarantine from 1st October.
But please be aware that nobody knows now how the vaccination 💉 or the number of people infected will be then. So this may change on short notice.
