The last few years we have taken DD to see a house near us that has a huge light display after dinner (we just walk around the corner). THey have a sausage sizzle and Santa and give out goodie bags to the kids. It's really lovely.
This year though that's thousands of kms away so not really sure. DH could also potentially be sent out bush this week, so we aren't planning anything.

I always watch carols though and let DD stay up late, and then I stay up much later to be Santa. Those are my favourite few hours of the year. I wrap pressies and set up toys, and leave out reindeer dust and chewed up carrot. Am panicking this year, because Santa is bringing a trampoline and if DH goes out bush I may have to erect it on my own.....
