very familiar with this hotel. It’s the only hotel in Thailand where the front desk staff (all women) hate foreigners and probably hate Asian foreigners even more than white people foreigners. This is of the top 2 worst hotels I have ever stayed at in Thailand. 35 years of visiting Thailand with my Thai wife.
This is only partially helpful. You gave a name of scams without explaining how the scam works. The gemstone scammer won’t say “I am doing the gemstone scam”. Same for the Tuk Tuk driver won’t say “I’m doing the tuk tuk scam”.
My daughters are Thai/US, born in US and have Thai passport and citizenship from the Thai embassy in Chicago and got their Thai ID cards in the Amphoe. Easier if you can write in Thai.
