We just returned from WDW and we used 2 umbrella strollers, one for our 5yr old and one for our 8yr old. There were sometimes when we were not spending the whole day in the park that my 8 yr old walked...but for the most part he used the stroller. It was much easier for my dh and i to maneuver them in strollers...when one was walking they couldn't keep up and it was so crowded that could have easily gotten lost in the shuffle.
