1200 for ASQ, 180 for Covid test, my insurance I pay every month 480 regardless of going to Thailand or not, coe and visa 80. My flight was 550 back and forth. Total would be 2010$ or 2490 if I count the insurance which I pay regardless of going to Thailand or not
3000 is excessive unless you staying in the Shangri-La or sth. I got in for 1500 and that’s with not staying in the cheapest ASQ hotel (but then, my health insurance already covered Covid internationally so didn’t have to buy a new one)
