I noticed you mentioned weather and wanted to tell you it can be iffy in December and to pack for all kinds of weather. It can be 80 dgrees one day and 30 the next. When we went in Dec 2006, it was cold all week. It started out just cold, then got colder as the week went on and I was in several layer with a scarf and gloves on our last full day. Then in Dec 2007, it was much nicer and I wore short sleeves and capris during the day and a lightweight jacket and jeans with the short sleeve shirt in the evenings.
