It has been at least 5 years since I was in Bangkok other than passing through the airport on my way to Cambodia or the UK. Man has it changed from my early recollections. I never did spend much time in Thailand, not really my favourite place. Stayed at The Miami Hotel, a little run down but comfortable and cheap considering it was right in downtown Bangkok.
Maybe I'm spoiled, but I found things, in comparison to Cambodia, expensive, booze, company and in general much more expensive than Cambodia, but they do have infrastructure, great rail system and the place is very clean on the streets, unlike Cambodia.
It was also very hot, the beginings of the hot season, to hot for carrying lots of gear around so I stuck mainly to a Canon 1D Mk IV and a Sigma 12-24.
