One of the best tips from my super-Disney Savvy aunts was to rent a stroller for the kids, who were 6 and 4 at the time.
There is a fee to rent the strollers from Disney but when you rent at least you don’t have to worry about someone stealing your expensive stroller or getting the stroller to and from the parks.
As you know, there is a lot of walking involved with the Magic. If you can swing it, rent a stroller. We did two single strollers instead of double stroller to eliminate fighting and because it is easier to maneuver single strollers than a massive doubler.
I thought Eli (6) would be offended by the stroller but he welcomed him as his legs tired very quickly at the parks.
Disclosure: I paid to attend the Disney Social Media Conference. In return, I received highly discounted park tickets, hotel, and a gift bag. There was no monetary compensation or posts required in exchange for this package.
What a great source of information! If you are touring these parks with children under 7 or 8 years old you will want a stroller. My 6 year old spent so much time in the double stroller from baby 7838 wheels last year it saved the trip. We carried all of our gear in the stroller and it was a perfect place for shade.
