Stopping for a day of sight-seeing in downtown Shanghai on another business trip to Hangzhou. The weather isn't too good and it's near freezing overnight. The skimpy heater in the hotel room has no chance against the cold, the poor construction standard and the 2 fronts of single-pane floor to ceiling glass. Even though the lady at the front desk doesn't understand, I am quite happy to trade my "executive suite" room for one of those stuffy window-less "basic rooms" in the center of the building. Next time, I shouldn't assume that sub-tropical means warm and dress for the occasion - like the locals do (they don't have much heat either...).
