We will be going to WDW in June. When we go, we will have a 6 year old and 3 year old. My 6yo is at the age when you think, "Does he REALLY need the stroller?" I'm really not sure if he will need one since he is a good walker. My 3yo will definitely need a stroller. We have a nice double stroller - nicer than the ones that we can rent. It is lightweight (well, as lightweight as a double stroller can be), and it is much more comfortable for the kids. However, I just don't know about dragging it around at the airport or even having to lug it with us all the time when I'm not sure our 6yo will even need it. Any thoughts?
