I've been talking to a number of people I know in Thailand... Test and go is up and running again (day 1 and day 5 PCR test to confirm no covid)... they will probably drop the 2nd test in the next 60 days. If you have not been to Thailand...; your life is not complete.
Bigbob62 is missing the best parts. Why take a holiday girlfriend when you can have 1-2 different girls each day. 1 USD = 32 Baht. Typical rates in pattaya for short time (1-2 hours) is 2000-2500B (that include the 500 bar fine to take the girl from the bar). Or you can use Thai Friendly and find lots of girls in the 2000 -3000 range for solid two hours. Rates are about 1000 higher in Bangkok and Phuket. You can of course get up to 6000 if you use online escort sites or go really high roller. Like this place
https://www.pimpbangkok.com/ best high end place IMO you can find in Bangkok. I plan to spend one night there with a couple of guys who will be in town.
For long time (usually afternoon till after breakfast give or take) it's 4000-5000B. The more days you keep a girl usually the price goes down. I have a trip planned in April for 10 days during their new year celebration. I expect to spend 4000 B (125 USD) - 9000B (280USD) a day depending on stamina for 2 different girls, with 2 girls at the same time, super top line girl, time spend in Bars and clubs, Thai friendly girls etc.
I plan on doing this too

You can go cheap 32USD hotel, 2500 ST girl /day or high roller 150USD hotel, 2x girls LT 280USD).
Singapore, Hong Kong, Shanghai, Taipei, have their fun but are nothing like Thai.. Don't like Thai women then look into Philippians. There are a few good places to go there too with good rates.
