Very few genuine tourists, without links to Thailand, are coming the reasons for this are the insurance required, $50,000 has to be stipulated on the document, which is not usually the case when buying a traditional insurance policy, and the having to pay again
for AXA Thailand (for example)
Also The word getting out about locking you up in hospital if you test positive.
The paperwork required to gain entry
No bars open
Genuine tourists will and are going elsewhere.
