Should I bring DS's car seat for the plane ride or have one less thing to carry/store? He just turned 2 so it's no longer required. We have a non-stop flight and we're using ME so no need for car seat at WDW? I really hadn't considered NOT taking the car seat (didn't occur to me) until DH mentioned that a car seat isn't required on the plane for kids over 2. What do you think?
