Aside from the annoyance of having to deal with childcare issues, I really like working on holiday weeks. It's like the funnest time to be working because:
1) There is so much food and treats everywhere. Yum.
2) Everyone is in a cheerful mood.
3) No traffic.
4) No trouble parking.
5) Generally tends to be easier, quieter days, at least where I work.
6) Excuse for any relative who complains that I'm not visiting: "Oh, sorry, I have to work!"
