Walk over to a couple of the many tourist information counters you will meet, when you walk around.

No matter what you want to do, you can get advise there, they are the most knowledgeable people about what is going on, at the destination.

Then you will get a real live person, to help you finding the best tours / transport or what your need, and if they don’t provide excellent service, easy to pick another.

They have the local knowledge about almost everything a tourist need.

Tours / transport can be booked just 1-2 days ahead, in that way, it’s possibel to take the weather in account, which you can’t do by booking weeks or month ahead online.

And as a extra bonus, you will support local people by dealing directly with them.

If anything goes wrong, you will know where to contact face to face.

Banks in Thailand are like everywhere in the world, interested in having good stable custormers, that have a permanent address, a steady easy traceable income, and use the account all year round.

That is why the banks are reluctant to give accounts to people on short time ( read: tourist ) visas which DTV is, and who only spend part of the year in Thailand.

Don’t expect to get a residence certificat, until you have stayed at a permanent adress in at least 3 month, since that is what the residence certificat should confirm.

Furthermore the added attention on whitewashing of money, is an added burden on the banks, so even depositing large amounts isn’t a guaranteed way to open an account.

The value of a resident certificat, had gone down, since Immigration Officers are giving them to people that are not on a longterm visa, or have stayed severel months at 1 adress in Thailand, so even if it is a formal requirement, the bank make up their own assesment of the stability of the want-to-be customer.

Copying anothers application can backfire.

As a tourist you don’t need a Thai bankaccount, and it will hard ( impossibel ) to get.

Reconsider if a Thai bankaccount is need-to-have or nice-to-have.

Ask the Thai Parlament.

If you’re in doubt, probably the Embassy will be in doubt too.
