Is December a good time to visit Taiwan?

At least one Singaporean blogger thinks so after visiting in December 2011 and again in December 2012. Not surprisingly, he and his family had better weather in the south than the north (winter days in Chiayi and points south are typically very sunny yet extremely comfortable in terms of temperature; nights are cool but not frigid). There's another reason why coming in December is a good idea: Relatively few Taiwanese travel at this time of year, so booking accommodation isn't difficult. The family especially enjoyed the night markets and the scenic hill town of Jiufen.
