I don't know how far it is, but taking a taxi even a long distance is cheap. Unbelievably cheap.

I took a cab from the Westin Sukhumvit in Bangkok to Pattaya for around $35USD. If I recall it was more than a two hour drive, closer to three. I was in a cab and told him I wanted to go to the bus station, he said I'll take you and I said no thanks. He then gave me a price and I starting converting in my head real fast. I thought I must be converting wrong because I knew how far it was.

Sure enough what a bargain for the convenience.
