I tend not to do long time in Bangkok, as that's where I go at the start of the holiday & I have jet lag.

For short time, my experience in Bangkok is of boys on Soi Twilight accepting 1500. Those on the phone apps often accept 1000~1500 ST.

Since 2000 is perfectly OK for LT in Pattaya, I struggle to see why more than 3000 should be necessary in Bangkok. Surely some on the phone apps or in the less fashionable bars should oblige ?

If not, settle for ST.
