And talk to your children, says Eileen Gunn, founder of FamiliesGo!, a family travel website.
"When the kids are 2 or 3 years old, they'll go along with whatever you say," even that Santa came early or is coming later, Gunn said. "At 6 or 7, they start asking questions. It depends on your kids, their ages and their inquisitiveness."
Drama may follow you on vacation
And remember you can't completely escape the family drama if you're traveling with the family that causes the drama (including yourself).
"You're not leaving everything when you travel with family," said Pauline Wallin, a psychologist with a practice in Camp Hill, Pennsylvania. "There's an initial settling-in period when everyone is nice to each other. The way you interact with family on neutral territory won't necessarily show up for the first 24 to 48 hours. After that, you become like your family is used to becoming. At least when it starts to grate on you (at a resort), you can retreat to the pool."
Just don't be surprised if Aunt Susie makes a comment about your weight or Uncle Harold teases you about not being married yet. "If you can predict this going to happen, why are you so surprised when it does?" asked Wallin. "Remember that Christmas Day is just 24 hours. You can get through 24 hours. People can hold it together when there's a time limit."
