My family is going to WDW for our first Christmas visit and are going to be at the Wilderness Lodge 12/16/17 - 12/26/17. I originally thought leaving to go home on 12/26 would be fine, but my mom has made me second guess this decision as she thinks the roads will be packed with everyone going back home from wherever they've been. She thinks we shouldn't leave until 12/27. As we all live in the same city, we have absolutely no experience with Christmas traveling crowds. Would really appreciate opinions from people who have experience with this. Should I keep our departure date at 12/26 or should I change it to 12/27?
