Cultural stuff near Pattaya, travel agencies, etc...

Hi guys.

Six days left until I'm off to Sin City again. This time I'm going to stay for a whole month. I'm pretty sure that I'll be bored after the first two weeks. So what else is there to do near Pattaya? I've already been to the Sanctuary of truth, the viewpoints, the area around "laser buddha", vine yards, etc... What else is near Pattaya?

So what else is there left to do? I thought about a little four-days side trip to Cambodia in order to visit temple ruins of Angkor. Has anybody some input on visiting Angkor and returning to Pattaya afterwards?

Also I'm looking for a trust-worthy travel agency that doesn't just dump you in a van with ten other farangs and rush you through some places. I'm looking for something like a list of places I could visit with a driver, so I could make my own time schedule. Any recommendations?

Cheers

U
