If you don't know don't comment
As the title says but commenting you are adding nothing but misinformation. 500 baht is standard at Gentleman clubs for a BJ. In Pattaya most expensive would be GoGo then bars like soi 6 then freelancers in clubs then Thai friendly then GC as that is standard at 1000 baht with a bit of ymmv mixed in.
My 2 cents on first visit
I did 1st visit to thailand last spring. If you have the time, I would recommend 10 days to 2 weeks and visit both pattaya and Bangkok. They both offer different opportunities and I enjoyed both. Easy and cheap travel between both. Bangkok is big city. I stayed between nana and cowboy so easy walk to both and to travel on BTS. Pattaya is beach town. And for me beach not beautiful to swim, is nice to walk and check out vendors and beach girls. I found pattaya a bit cheaper and easier to get around. I did Pattaya 1st and when I return I will spend most time in Pattaya. You will have fun, experiance all you can.
