My DW and I keep going back and forth on this one. Our DS will be 4 1/2 years old on our next WDW trip at the end of this month. We have always brought a stroller with us but this year we are wondering if he will need one. We think he will because of all the walking that we do (like everyone) at WDW. Although he wouldn't be in the stroller all the time, it may be good for when he is tired and needs a break from walking. Any thoughts?
