How nice of you to include all the holidays! After reading the responses below, I think I should invest in a pajama company!
We're Jewish and we have managed to accumulate a small supply of fun Hanukkah lights as well as 3 or 4 banners that say "Happy Hanukkah" but each with a different spelling! We have a good laugh trying to hang them in appropriate places based on the length and the number of English letters (Hannukkah vs. Hanuka, for example).
I think my favorite thing is getting out all our menorahs. While 1 is "required", more are acceptable. We have our original family menorah (which I bought my husband for our first holiday), a whimsical one that he bought for me, and our son's first menorah (a train with different candle holders on top of the cars, with the smokestack serving as the holder for the tallest candle used to light the others). We also have one that our son made in preschool out of large wooden beads (the candles go in the holes) and another one he made for me almost entirely on his own (with a little finishing help from Dad) - it's out of scrap wood, and he used a bunch of hex nuts glued to the wood as the candle holders. He took a bunch of little nails and some colored thumbtacks (the old kind with flat heads, not push pins) and he hammered a menorah shape and the word "Mom" into the wood. It's so special to me! We line them all up on the living room window sill (we have a bay window) and we light them all up as we sing the blessings, and each night there is more and more light to share with the neighborhood.
We also do Chanukah gelt (the chocolate coins in gold foil) which my son still loves after all these years - he gets a little bag of 6 or 7 coins every night. I made a wall hanging with 8 numbered pockets and a little gift goes in each pocket. We usually do a book, a movie ticket, socks, maybe a DVD, and other little things, whatever appeals to us. It's not a big gift fest and we try to keep that under control.
At least one night is something community oriented, either a party with friends/family or something at the synagogue, but with some community service included, whether it's a food drive or a clothing drive or something else. We like to include our non-Jewish neighbors and friends - we find that sharing holiday traditions builds appreciation and respect. Coexistence and religious integrity is, after all, the basis for Hanukkah so we like to have discussions about those who are, even in the present day, being pressured to adopt a majority religion in their country, whether it's the US or somewhere else. Building bridges and honoring our differences while appreciating our similarities is what it's all about.
And of course we have our favorite fried foods all week, with regular or sweet potato latkes, sufganiyot (jelly donuts), falafel, and our own chicken tenders or nuggets. Definitely requires at least one stop at the supermarket for more olive oil!
We also enjoy driving around to see other people's Christmas lights. And on Christmas Day, we join hundreds of other Jewish families at the movies and then one of the Chinese restaurants. It's always fun to see people from surrounding towns that we may not have seen since last Christmas Day.
