Just what was "bad" ( for farangs ) about Pattaya in early 90s? The great stink was gone, the beach walkway was actually pleasant to walk along, traffic was within reason given size of roads, no wanabe farangs dressed up like cops, though Walking Street had yet to eventuate, and even when it did they didn't for some years, crime against farangs was minimal, baht buses were cheap, I don't recall floods on the scale of now, Buakhao was just a narrow street somewhere, and people were mainly happy, far as I saw.
While it was many years ago, my memory isn't so bad that I'd only remember the good bits. If I had any complaint about those times, it was that the bus service from Ekamai took over 4 hours and the buses were apparently rejects from other companies.
