I've been going to Pattaya since 2003 and I really do not see what you see.
I see lots of organised golf, plenty of western restaurants, Thai street food, western street food, markets everywhere you look. Oh and there's a sex scene that's gradually pushed out past Second Road to Soi Buakhow and even Third Road and if tourism picks up and is successful it may even get pushed out to Sukhumvit Highway.
I'm stunned that all you saw was sex tourists.
Define sex tourists? My first 2 visits to Pattaya were for work and then a visit to Bangkok for work. Went back to Pattaya twice after to spend time with my then Thai girlfriend and discovered golf. I was hooked. A few failed relationships along the way, 1st time marriage at 51, first child at 52. What more could I ask?
By the way I've lost count but I've easily been to Thailand 70-80 times with most of those visits including Pattaya. I'm not a sex tourist am I?
My friend is 64 years old and he plays golf and he's now retired in Thailand. He lived in Pattaya, then Jomtien and now built a house out Ban Chang way. He's been with a Thai caddie for the past 5-6 years. Sex tourists?
Another friend is 74. He's been with a Thai lady 15 years. He has made so many friends there that there's usually a decent size group at the Aussie bar drinking and telling yarns. Sex tourists?
The guy that used to own the golf bar where I play golf came to Thailand nearly 30 years ago with GBP 2000 and he built a successful business that's still going today. He passed away a few years ago. Sex tourist?
Pattaya can be a very lovely place if you know where to go.
If you and your friends are paying for sex, then you are sex tourists.
