I used to go there a couple of times a year and I had a ball.
Before Pattaya it was Phuket which I grew out off after a few years.
World class? no I doubt it but Thailand is what it is.
Beaches ain't flash but the tourist attractions like night life, pussy and cheep smokes is fair, far better places in Australia for sight seeing but Aus in not for the budget conscious.
Not been to Pattaya for five years as I prefer the quiet life upcountry.
