[QUOTE=Philodemus;29908491I wonder whether you hit a particularly hot period or a defective air conditioner, though the fact you had the problem twice does seem to make this less likely.[/QUOTE]

Not especially. Normal Thailand hot. 32+ during the day.

Also, both hotels acted as though nothing was up and all they did was turn the thermostat down to 10 degrees (which makes no difference, of course, on a simple on/off thermostat) and shut the bathroom door.
