When you say wrong-uns, could you elaborate more? I’m planning a visit in Nov/Dec.
What StickItIn said and also, Pattaya is attracting a lot of foreign tourists from neighbouring countries at the moment (others put off by Thai Pass, China not allowing anyone out etc.) that have no manners in anything. They're loud, rude, irritating as f*ck and just generally unpleasant to be around. And they're everywhere.
But if you go in November you're hitting peak season and so hopefully you'd some of them.
I do like Pattaya - so long as you're careful it's safe, the women can be gorgeous and it's cheap. But you get what you (and others) pay for...
