The last time we went to WDW when our son was 4, getting a stroller was a no-brainer. This time, however, he is 6, and I am questioning whether or not to be thinking about stroller. Any advice from parents who have experienced WDW with a six year old, and how you handled it would be appreciated. I know he would not use it all the time, but will a six year old get tired enough to want to use it as needed? Thanks for any help/advice!
