Invite your family and friends to have a party at your place and stay for the night. You may choose to do some things together like decorating the living room and Christmas tree or baking. It is more inspiring and merry to do it together rather than to prepare everything yourself in advance.
After it you can have a heart-to-heart talk while enjoying delicious dishes and sweets you have just made. Add some warming drinks spiced with fair Christmas stories and the party will be just awesome.
