You could always make this the year that you start your own Christmas traditions. Even though DH and I have a big family xmas, we like to have our own little tradions too, for eg, on xmas eve we make cookies which is a tradition we hope to keep up when we have kiddies. They can leave their cookies out for Santa!
We also make a big deal out of putting up the xmas tree...... wine, nibbles, music etc
Plus, make sure you keep the excitement about opening presents on xmas morning, get up early, surprise each other, have a nice breakfast.
And if you're religious, go to church, midnight mass etc as I find it really Christmasy
Just a few ideas .........
