In the past I've gotten them out by about the first week of December, but this year I'm sending them later...December 16, the day before we leave for WDW. It's at DS's request...he doesn't want his paternal grandmother hounding about not being at her house this year for the holiday. She was unbelievable for Thanksgiving...really piled on the guilt to the poor kid. He's only 13 and the only grandchild until April. DS tries to be polite and not be disrespectful when he speaks to her, but being nice isn't understood so he'd rather not have to deal with her for Christmas.
So, the cards will go out in time to let her know that we're gone and she can't lay a guilt trip on her grandson.
