We just did Disneyland a few weeks ago and took our 5 year old in a stroller albeit one we rented from them however have previously taken the large stroller of our own. In our case we received a special needs pass due to my child's abilities so we were able to keep the stroller with us throughout lines and other things. However, even if we could not do that I still would've preferred to use a stroller because Disneyland is huge and while fun is very tiring on adults with all the walking and standing in line let alone a young child. I would say definitely take it.
